Global cropland-N2O emissions dataset (1901-2014)

Global
gridded cropland-N2O emissions dataset

Data Products:
1. Global gridded dataset
of N2O emissions from upland crops (5-arc-minute, annual) during the period 1901-2014.
2. Global gridded dataset of N2O emissions from paddy rice (5-arc-minute,
annual) during the period 1901-2014.

Note: The datasets were produced by using flux upscaling approach (BRRTv2) by Qihui Wang at Peking University. Detailed informations such as variable names and units can be obtained by using
the “ncdisp”function in matlab.

Resolution:
5min;
Latitude:
90°N~90°S
Longitude:-180°W~180°E
Variable
name: N2O_FI_r; N2O_FI_u
Definition:
N2O_FI_r means fertilizer induced N2O emissions by paddy rice and N2O_FI_u
means fertilizer induced N2O emissions by upland crops
Unit:
kg N per ha per yr; kg N per ha per yr
The
“ha” stand for paddy rice area for paddy rice emissions and upland crops area
for upland crops emissions.
