I used to work with UDEL grid estimate (look here) data where station values of monthly total raingage-measured precipitation (P) were interpolated to a 0.5 degree by 0.5 degree latitude/longitude grid, where the grid nodes are centered on the 0.25 degree. However, after I tried to interpolate those data with Germany NUTS3 district only, and I got a poor match because I need to calculate population weighted yearly average for each Germany NUTS3 polygon but some polygon lost population data which affect my expected output. Now I realized that chosen grid estimate data is not precise enough which caused this problem.

I used to work with UDEL grid estimated data with 0.5x0.5 degree resolution (http://climate.geog.udel.edu/~climate/), but it is not ideal for my research. I used also DWD station level data (DWD station level data link), but this dataset also won't fit my expectation.Now I am looking for a grid climate data (Temperature/precipitation data) with the better resolution.

Now I am looking for the grid climate data with better resolution, where 0.25x0.25 degree grid data of global climate (land surface temperature/precipitation) are desired. Where can I find free open source grid climate data that meet my specification? Anyone know a possible source where I can download such data? Possible help would be appreciated.

  • You may want to look at ARM data. Better resolution, but unless things have changed it is not global... arm.gov/data – Christopher Klaus Apr 23 '18 at 13:36
  • @ChristopherKlaus Thanks for your prompt hit on my question. Actually, I am looking for grid level data for Germany with 0.25x0.25degree spatial resolution. Could you give me possible help with that? Thanks – Jerry Apr 23 '18 at 13:39
  • Unfortunately, it’s been a decade since I’ve done research with atmospheric data. I’ll take a look later today to see what I can find. =) – Christopher Klaus Apr 23 '18 at 13:45
  • Note sure if our gap-free global time series of land surface temperature from MODIS LST data (5.6 km pixels) would be of interest: zenodo.org/record/1135230 – markusN Oct 25 '18 at 10:08
