It's not always easy finding good environmental spatial data for a project. Fortunately, the links below are a great start to quality, open-sourced global environmental data.
Climate Data
WorldClim version 2 has average monthly and annual climate data for minimum, mean, and maximum temperature and for precipitation for 1970-2000.
You can download the following variables for different spatial resolutions, from 30 seconds (~1 km2) to 10 minutes (~340 km2):
minimum temperature (°C)
maximum temperature (°C)
average temperature (°C)
precipitation (mm)
solar radiation (kJ m-2 day-1)
wind speed (m s-1)
water vapor pressure (kPa)
Global Aridity Index and Potential Evapotranspiration Climate Database v2 provides high-resolution (30 arc-seconds) global raster climate data for the 1970-2000 period, related to annual and monthly potential evapotranspiration processes.
Soil Data
ISRIC, the World Data Centre for Soils (WDC-Soils) provides a wide range of soil information and data. The following links lead to data on soil classification, nutrient content (nitrogen, phosphorus, carbon, organic carbon and calcium carbonate), bulk density (in different conditions), cation exchange (at various pHs), electrical conductivity, water retention and more!
WoSIS is ISRIC's central data base with soil class and property information from more than 100 000 soil profiles around the world.
SoilGrids is a system for automated soil mapping based on global soil profile and environmental covariate data at 250 m spatial resolution.
ISRIC Soil Data Hub is ISRIC's soil metadata catalogue - another resourceful avenue to explore for soil data.
Hope this is useful!
