Precipitation - daily unvalidated precipitation sum in near real time
-PROVISONALLY UNVALIDATED DATA- Gridded files of daily unvalidated precipitation sum in the Netherlands measured on 100-300 locations of the voluntary network from 08:00-08:00 UT. Grids are calculated based on unvalidated data (limited number of stations) as soon as the data is available, typically around 14:00. The data has only been automatically pre-validated. The complete validated dataset is Rd1. Version 2 is based on RobuKIS source data.

The interpolation method is ordinary kriging. Observations are square root transformed and back-transformed after interpolation using quantiles calculation. For every day a variogram is automatically fitted. The nugget is zero and the variogrammodel is spherical or exponential, depending on the best fit. The dates in the file name refer to the end-time and start-time of the measurement. The measurement at 08:00 UT (end-time) is assigned to the file in the folder of the preceding day on the FTP server as 2/3 of the measurement period falls on the preceding day. In other words: the measurement with the end-time 19810102T080000 is assigned to the folder 1981/01/01 on the FTP server or in the tar-file. The number of observations varies from 100 to 310. Therefore the dataset may be less accurate than the validated dataset (Rd1).
