Datasets:
- TerraClimate
Description: Climate and climate water balance dataset for terrestrial surfaces based on WorldClim and CRU Ts4.0 and JRA55
Organization: University of California Merced (UCM)
Website: TerraClimate Website
Google Earth Engine:
Spatial resolution: 4-km grid (1/24-deg)
Time Span: 1958 to Present (monthly data, updated every year)
Variables:
- Actual evapotranspiration
- Climate water deficit
- Palmer drought severity index (PDSI)
- Reference evapotranspiration(ASCE grass/alfalfa)
- Precipitation accumulation
- Runoff
- Soil moisture
- Downward solar radiation (W/m^2)
- Represents the mean of the downward solar radiation over all the days of the month, where it's reflecting the average over all hours of the day.
- To go from Watts/m^2 to MJ/(m^2day) you need to multiply the number of sec in a day: watts/meter² x 86400 s/day x 1 MJ/10^6 J = MJ/(meter²*day).
- Snow water equivalent (for the last day of the month)
- Minimum/Maximum Temperature
- Vapor Pressure
- Vapor Pressure Deficit
- Wind Speed (10-m)
