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 vailable, typically around 14:00. The data has only been automatically pre-validated. The complete validated dataset is Rd1. ---- KNMI has detected measurement anomalies caused by a defect in some rain gauges for manual precipitation observation. It concerns data from the second half of 2012 until present. At this moment KNMI is assessing the extent of the problem and investigates the options to repair the defect as soon as possible.

Linage statement 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).
