The Oury index is an aridity index that combines temperature and precipitation to connect climatic effects to crop growth.
JournalMap searchers can narrow searches based on location and biophysical variables, including climate (precipitation, temperature, growing-degree days, aridity index), landform (elevation, slope), soils (surface texture, depth), and landcover (biome, landcover type).
Aridity index is 0.33, the mean temperature during the months of winter is 6[degrees]C whereas during months of summer is 24.5[degrees]C [5].
The environmental factors tagged in JournalMap include climate variables such as daily temperatures during the growing season, average annual precipitation, and aridity index; landform characteristics, such as elevation and slope; soil characteristics, such as surface texture and depth; and types of land cover.
The evaluation indexes include the frequency of dust storm, mean minimum temperature, mean maximum temperature, average diurnal temperature difference, cold disaster frequency, aridity, variation rate of aridity index, the frequency of spring drought, the frequency of summer drought, the frequency of cold disaster, and so forth.
Precipitation and temperature data of 18 years (1988-2005) is used to compute Modified Fournier Index (MFI) and Bagnouls-Gaussen aridity Index (BGI) that is overlaid to generate erosivity map.
