Period: 2000 – present Sensor: MODIS Terra+Aqua Frequency: Yearly Resolutions: 500m Extent: Global Data can be accessed here. Algorithm description: MOD17A3H V006 MODIS annual NPP product is derived from 8-Day composite MOD17A2H product, which is 8-Day GPP composite, but it also consists of Net photosynthesis (PSN). NPP is calculated as PSN – Maintenance respiration (MR). The method is based on ‘radiation conversion…
Period: 1999 – present Sensor: SPOT-VGT and PROBA-V Frequency: 10 days Resolutions: 1km Extent: Global Data can be accessed here. Algorithm description: Ten day composite of GDMP (gross dry matter productivity) and DMP (dry matter productivity). Both quantities are expressed in units of dry matter instead of kg of C (unit: kg of DM/ha/day). The algorithm calculates GDMP based on Monteith theory of light…
Period: 2014 – present Sensor: PROBA-V Frequency: 10 days Resolutions: 300m Extent: Global Data can be accessed here. Algorithm description: Ten day composite of GDMP (gross dry matter productivity) and DMP (dry matter productivity). Both quantities are expressed in units of dry matter instead of kg of C (unit: kg of DM/ha/day). The algorithm is same as that used for Copernicus 1km DMP and GDMP…
