SACRA: Global data sets of satellite-derived crop calendar for agricultural simulations

■Brief Description



This web-site presents a new global data set, the SAtellite-derived CRop calendar for Agricultural simulations (SACRA). Using the time series of NDVI averaged from three consecutive years (2004?2006), sowing/harvesting dates are estimated. Details of the data sets can be found at the reference (Kotsuki and Tanaka, 2015; HESS).
