Global cropland-N2O emissions dataset (1901-2014)

<b>Global gridded cropland-N2O emissions dataset</b><br> <b>Data Products:</b>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.<br>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.<br>Resolution: 5min;Latitude: 90°N~90°SLongitude:-180°W~180°EVariable name: N2O_FI_r; N2O_FI_uDefinition: N2O_FI_r means fertilizer induced N2O emissions by paddy rice and N2O_FI_u means fertilizer induced N2O emissions by upland cropsUnit: kg N per ha per yr; kg N per ha per yrThe “ha” stand for paddy rice area for paddy rice emissions and upland crops area for upland crops emissions.<br> <b>Citation:</b>1.
