Useful Datasets

The below datasets or documentation are open to all. Hope it will benefit your research.

Climate

• National Centers for Environmental Predictions (NCEP) Reanalysis II: air temperature, precipitation water, and other meteorological variables at various pressure levels (daily & monthly over 1979–present; 2.5º-by-2.5º) [Kanamitsu et al, 2012]

Ammonia (NH₃)

• IASI satellite-measured column concentration (0.01º-by-0.01º) [Van Damme et al. 2018]

• Ammonia Monitoring Network (AMoN) in situ ground measurement of the 2-m concentration (site data) [National Atmospheric Deposition Program 2014]

• MASAGE_NH3 – a global agricultural emission inventory (monthly; 2º-by-2.5) [Paulot et al. 2014]

• A Chinese agricultural emission inventory by Peking University (monthly; 0.5°×0.667°) [Zhang et al. 2018]

Nitrogen Dioxide (NO₂)

• Gridded concentration derived from OMI satellite measurement by the University of Wisconsin-Madison (monthly over 2006–2018; 12 km-by-12 km) [Harkey et al. 2015]

Fine Particulate Matter (PM_2.5)

• A global concentration estimate based on the Bayesian hierarchical model (annually over 2010–2016; 0.1° × 0.1°) [Shaddick et al. 2018]

Agriculture

• Crop calendar dataset by the University of Wisconsin-Madison (5'-by-5' & 0.5º-by-0.5º ) [Sacks et al. 2010]

• Harvest area and yield for 175 Crops by EarthStat (for the year 2000; 5'-by-5') [Monfreda et al. 2008]

• Crop allocation to food, feed, and nonfood by EarthStat (5'-by-5') [Cassidy et al. 2013]

• Nutrient Application for Major Crops (for the year 2000; 5'-by-5') [Mueller et al. 2012]

Soil

• Harmonized World Soil Database v1.2 [Fischer et al. 2008]
  • Land mask, terrain elevation, slope  (30"-by-30" & 5'-by-5')
  • Land use and land cover: rain-fed cultivated land, irrigated land, forest land, grass/scrub/woodland, built-up land (residential/infrastructure), barren/very sparsely vegetated land, or water bodies  (5'-by-5')
  • Soil qualities for crop production: nutrient availability, nutrient retention capacity, rooting conditions, oxygen availability for roots, excess salts, toxicity, and workability (5'-by-5')

Geography

• GADM database of Global Administrative Areas (shapefiles; check out my GitHub repo on how to use it in R)
