Im wondering if anyone has come across any data source that can be used to calculate the number of days where temperatures are greater than 0 degrees C, 10 C and 20 C at a global scale? I have a site matrix of ~200 sites and would like to extract these data for each site. Any recommendations on how to do it?
The National Snow and Ice Data Center has a dataset along these lines. NSIDC Dataset
The problem now becomes, how do you convert a .dat into a usable
writeRaster but this wont work for me. Any suggestions?
