Where can I find gridded Current Global Climate Datasets (Mean Temperature and Precipitation) at 30 second resolution?
I think that http://www.worldclim.org should do the trick as they offer datasets in different resolutions including 30 sec.
for the land-masses you can find the data here: http://climate.geog.udel.edu/~climate/html_pages/download.html http://climate.geog.udel.edu/~climate/html_pages/download.html#T2014 gives you gridded monthly Air Temp for the years 1900 to 2014 and http://climate.geog.udel.edu/~climate/html_pages/download.html#P2014 gives you gridded monthly Precipitation for the years 1900 to 2014 the format is good documentated and you can easily construct different normal-climate-periods e.g. 1981 -2010, 1931 - 1960 ...
Global Solar Atlas features with global raster dataset of long-term average of air temperature, 30 arcsec, currently calculated for a period 1994-2015. Data source are CFSR and CFSv2 data from NOAA, postprocessed by Solargis. All metadata is included, follow:
- or the same data at http://solargis.com/en/maps-and-gis-data/download/world
Precipitation - very reasonable quality raster data is provided by DWD within a GPCC (Global Precipitation Climatology Centre) project. Monthly, daily and various aggregations available. However, the resolution is coarser (check the latest release of data). Follow
