The OTT Pluvio2 Version 400 is an all-weather precipitation gauge that measures the amount of precipitation using the weighing principle. It measures the weight of the collecting bucket including its content. The difference between the current bucket content and the previous one recorded gives the precipitation amount. The data set includes the non-real-time output of the OTT software which is particularly suited for daily and monthly totals. The non-real-time output provides a more precise precipitation sum due to better filtering: fine precipitation is collected over a maximum of one hour and output after reaching the threshold of 0.05 mm within that hour. If the fine precipitation does not reach the threshold within an hour, there will be no output. The resolution of the precipitation values is 0.01 mm. The measurement uncertainty is the larger value of ± 0.1 mm or ±1%. In each of the datasets for the years 2017-2021 daily netCDF files are provided.
