During the monitoring period, NDVI was close to the previous five-year average except for early October, late December and early January. The rainfall was above average (RAIN +21%), while the temperature and radiation were below (TEMP -0.2℃, RADPAR -8%). The cropped arable land fraction was well above average (CALF, +29%) and so was the biomass accumulation potential  (BIOMSS +36%). The maximum VCI (VCIx) reached 0.93.

NDVI was close to and above average throughout the reporting period in Yunnan Province. Other Provinces (Guangxi, Guangdong and Fujian) had below average NDVI from late December to 2019.  The potential biomass departure map shows below average values exceeding 20% in most of Guangxi and Southwest of Guangdong. 

The good climatic conditions were favorable for the crop production.
