Report on the validation of the HIC rain gauges data of 2019 Michel JournĂŠe, Royal Meteorological Institute (RMI)
Abstract This report summarizes the results of the validation of the data recorded during the year 2019 by the 19 rain gauges operated by HIC. This validation is made by RMI and integrates two aspects. First, a human operator routinely monitors the data on successive periods of 24 hours.
Issues
detected on that daily timeframe are directly corrected. Second, monthly and annual values from the validated HIC data are compared against neighboring stations data as well as radar-derived rainfall estimates. Both validation aspects are treated in this report.

1. Introduction This report summarizes the results of the validation of the data recorded during the year 2019 by the 19 rain gauges operated by HIC. This validation is made by RMI and integrates two aspects. First, a human operator routinely monitors the data on successive periods of 24 hours.
Issues
detected on that daily timeframe are directly corrected. Second, monthly and annual values from the validated HIC data are compared against neighboring stations data as well as radar-derived rainfall estimates.
Both validation aspects are treated in this report: in Sections 2 and 3 for
the routine daily validation and in Sections 4 and 5 for the comparisons at monthly and annual timescales.
Precipitation overview in 2019 in Belgium The annual rainfall in 2019 in Uccle is with 798.6 mm slightly below the 1981 2010 normal value (852.4 mm). This precipitation quantity is distributed on 182 precipitation days (normal value: 198.7 days), as shown in Figure 1, (left panel).
The monthly precipitation values in Uccle are
below the monthly normal values for 8 months, i.e., all months except February, March, June and October (Figure 1, right panel). In the climatological stations located in the Flemish Region (around 90 stations), the annual total varies between 630 mm (in Poperinge and Ransberg) and 940 mm (in Diksmuide and Ingelmunster) and is in most places below the 1981 2010 normal values (Figure 2).

2. Data validation method The Royal Meteorological Institute (RMI) is in charge of the validation of the 5-min timeseries of the HIC rain gauges since January 1, 2019. RMI has a solid experience in meteorological data validation, and in particular in rain gauges data validation. Rain gauges observations in Belgium are veri ed routinely at RMI as an operational task. Each business day, an operator checks the latest rain gauges data with the help of data visualisation and manipulation tools. These tools are internally developped and accessible within a user-friendly interface named
PluvioControl.
The validation procedure is semi-automated
in the sense that suspicious values are highlighted by this tool and proposed to the operator for further checks who takes the nal decision to validate or to correct these values. PluvioControl allows the operator to interact with observations from automatic rain gauges (5-min data) as well as manual rain gauges (daily precipitation totals). Till the end of 2018, RMI performed a routine validation of the rain gauges data recorded within the Belgian climatological network (around 200 stations), by 15 automatic rain gauges in RMI stations and by around 90 weighing rain gauges operated by the Walloon hydrological services.
Since January 2019, rain
gauges data from the HIC stations have been integrated in this routine validation. Because the daily observations in the Belgian climatological network are made each morning at 08:00 (local time), the validation of both manual and automatic rain gauges is made on periods from 08:00 on a given day to 08:00 on the next day. In this way, daily totals from automatic rain gauges can be accordingly compared to daily values from manual rain gauges. Each business day D, the data received since the previous validation period till 08:00 on day D are veri ed (i.e., on Mondays, data from Friday 08:00 till Monday 08:00 are typically veri ed, while an Tuesdays, the validation concerns the data from Monday 08:00 till Tuesday 08:00). The following tools are available in PluvioControl to detect suspicious values:
An overview provides various statistics about data availability.
Interactive maps (based on the Google maps API) allows a spatial visualization of daily and

hourly precipitation values (Figures 4 and 5).
These values can be compared across the
various observation networks. Overlays with radar accumulation products as well with cloud masks derived from Meteosat Second Generation data are also available.
For each stations, time series plots compare hourly and daily values against corresponding values from neighboring stations (i.e., against an inverse distance weighing interpolation of the 5 closest stations) and radar data (Figure 6).
A set of statistical plausibility tests performed at various timescales (5-min, 1-hour and daily data) enables to highlight suspicious cases.
For each station, a spatial analysis lists the daily totals from the closest rain gauges. Data from the rain gauges operated by VMM are available in PluvioControl even if these data are not checked for inconsistencies.
As snow can be an issue for precipitation observations (especially for the previous tipping bucket rain gauges), all available observations regarding snow (snowfall and snow depth) are centralized in a page of PluvioControl.

With the help of these tools, the operator checks all suspicious cases one by one and corrects the data when necessary. Corrections can be applied directly on the 5-min data. Alternatively, corrections can also be set for hourly or daily totals and then automatically reported on the 5-min data.
Missing data are systematically lled with estimations which are mostly based on
neighboring stations data. The operator has however the possibility to use radar estimates instead, which are is some cases more appropriate (e.g., case of small-scale convective precipitation). Once

The 5-min time series of the 19 HIC rain gauges represent almost
values in 2019. The heat
maps in Figures 7 and 8 provide some results regarding the validation of these time series. These plots illustrate for each station and month the amount of valid, missing/unfeasible, suspicious and erroneous data. Unfeasible 5-min data are those that are negative or larger than 50mm. Erroneous values are values between 0mm and 50mm that had to be corrected. a. Amount of valid data (%)

The results in Figures 7 and 8 indicate that most of the data (i.e., 99.6%) are considered as valid. The remaining 0.4% of data are mainly missing data (0.37%) for which estimations have been provided.
Suspicious data are quite rare and correspond to small non-zero precipitation
values recorded during dry periods (according to both neighboring station and radar data), i.e., so-called phantom precipitations.
Erroneous data are also rare and are of 2 types: small non-
zero precipitation values during dry period (phantom precipitations) or excessively large values con rmed neither by neighboring stations not by radar data. Phantom precipitations are a wellknow potential issue of OTT rain gauges (depending on the rmware version) but are not really of concern for the HIC network as this problem occurs infrequently.
4. Comparative analysis against neighboring stations In this section, the validated data of the HIC rain gauges are compared against data from neighboring rain gauges.
For each HIC station, the 4 closest stations with complete and validated
time series in 2019 are considered. These neighboring stations are either RMI stations (manual or weighing rain gauges) or OTT weighing rain gauges of the Walloon hydrological services. When comparing observations from di erent sensors and location, it is important to keep in mind the recommendations of the World Meteorological Organization (WMO). The WMO de nes for all meteorological measurements an
achievable measurement uncertainty
which is based on
sensor performance under nominal and recommended exposure that can be achieved in operational practice. It should be regarded as a practical aid to users in de ning achievable and a ordable requirements (WMO, 2018).
In the case of precipitations, the recommended achievable mea-
surement uncertainty is the larger of 5% or 0.1 mm . In Figure 9, annual totals derived from the validated 5-min time series of the 19 rain gauges are compared against annual totals from neighboring stations. The blue errorbar displays deviation of
Âą5%
around the annual total of the HIC stations in order to highlight the WMO recommended
achievable measurement uncertainty.

cipitation events inducing signi cant di erences in daily precipitations for some speci c days. The annual number of precipitation days based on 4 threshold values (i.e., number of days with at least 0.1, 1, 5 and 10 mm precipitation) are compared in Figure 10 against corresponding values of the 4 neighboring stations. Regarding the lowest threshold at 0.1mm, the number of precipitation days in the HIC stations matches well with those in neighboring stations. For the other thresholds, the values in the HIC stations are either within or below the range of those in neighboring stations. A station-wise comparison of the monthly number of precipitation days is provided in the Appendix A. These graphs do however not highlight any speci c issue.

5. Comparative analysis against radar data In this section, the validated data of the HIC rain gauges are compared against radar-derived ground rainfall data. Annual and monthly radar-based precipitation totals are derived for the 19 locations of the HIC rain gauges from the daily composite RADQPE radar product (Goudenhoofdt, 2019). This RADQPE product results from an advanced processing of the 3D radar re ectivity measurements including beam blockage correction, mitigation of non-meteorological echoes, precipitation classi cation and correction for the vertical pro le of re ectivity. The rain rates are accumulated over a given duration by taking into account the movement of precipitation. The estimates are then adjusted to rain gauge measurements using a single bias correction. Estimations from single radars are combined into a composite using a distance-weighted scheme for the cold months and by taking the maximum value for the warm months. The composite product considered in the comparisons below integrates data from the radars of Wideumont, Jabbeke and Avesnois. The

average radar bias is estimated based on the automatic rain gauges operated by RMI, SPW and VMM. The annual total of the 19 HIC rain gauges are compared against corresponding radar-derived values in Figure 11. The annual radar-based values overestimate the ground observation by 6% to 28%. This overestimation is not speci c to the HIC rain gauges as shown in Figure 12 with RMI stations located in the Flemish Region.
In spite of this overestimation, the radar-derived
values reproduce quite well the station-wise variability of the observed annual totals at the 19 HIC stations (Figure 11).

In spite of the limitations inherent to remote sensing observations, the radar data allows to compare the various rain gauges against a same reference.
These analyses do not highlight
speci c outliers in the monthly and annual values of the HIC stations.
6. Conclusion The routine daily validation of the data of the 19 HIC rain gauges indicates that most values are valid and corrections mainly concern missing values. Erroneous values are infrequent and either related to small non-zero values in dry periods (i.e., phantom precipitations) or excessively large values. The daily validation enables to highlight and correct issues that can be detected when analyzing 24 hours of data. Issues such as small but persistent biases or drifts need however longer time frames to be detected. It is therefore useful to complement the routine daily validation with a comparative analysis of monthly and annual values. This report therefore also summarizes comparative results of monthly and annual values derived from the validated HIC data against neighboring stations data as well as radar-derived rainfall estimates. These validations did not highlight speci c issues in the HIC data. When comparing the HIC data against neighboring stations data in terms of monthly and annual precipitation totals or precipitation days, it appears that the HIC values are either within the range of neighoring stations or below this range, but rarely above it. A slight under estimation for some HIC rain gauges is thus possible but di cult to assess. It should be noted that comparisons between parallel observations made with several rain gauges (manual and weighing rain gauges) located just a few meters away from each other in Uccle highlighed di erences up to 5% between these rain gauges. Observations made with the automatic weighing rain gauges were on average slightly lower than those made with the manual rain gauge. Finally, in addition to the measurement uncertainty related to the sensor performance, there are uncertainties related to the in uence of the close environment of the rain gauge on the measurements. In this context, WMO de nes a siting classi cation (WMO, 2018b). RMI automatic rain gauges are classi ed either as Class 1 (i.e., reference site) or Class 2 (i.e., additional estimated uncertainty added by siting up to 5%). For sites of Class 3 , Class 4 or Class 5 , an additional estimated uncertainty added by siting has to been into account that ranges up to 15%, 25% or 100%, respectively.

A. Comparative analysis against neighboring stations: results per HIC station This appendix provides detailed comparison results of the validated data of the HIC rain gauges against data from the 4 closest stations with complete and validated time series in 2019. These neighboring stations are either RMI stations (manual or automatic) or weighing rain gauges from the Walloon hydrological services (SPW). For each station, 4 types of graphs are provided: - cumulative precipitation plots, - bar plots of monthly totals, - scatter plots of daily values, - bar plots of the monthly number of days with 0.1, 1, 5 and 10mm precipitation (orange dots represent corresponding values of the 4 neighboring stations).
