This analysis covers thelate stages of maize and sunflower seed (October harvest) and the earlyvegetative stages of winter wheat and winter barley. The CropWatch environmentalindices show slightly decreased rainfall (-2 percent) and slightly increasedPAR accumulation (+4 percent) compared with the recent five-year average at thenational level. Although the temperature is below zero with -3.5℃,it is still 2℃ above the five-year average, which is consistent withthe warmer-than usual weather condition reported by NOAA NCDC climate anomaliesand JRC/MARS bulletin. The national biomass is estimated increasing by 4percent compared with recent five-year average. According to the NDVI profiles,NDVI dropped sharply from November and remained below the average until lateDecember. This might contribute to the above-average precipitation during thisperiod, which contaminated the NDVI value to a certain degree. According to theNDVI clusters, most of the crop growing areas in the southwest of Russiaexperienced below average NDVI values from late November to late December,especially for the south of Southern Region (including Stavropolskiy kray,Karatchayevo-cherkesiya rep., and Kabardino-balkariya rep.) and the southwestof Volga region (Volgogradskaya oblast and Saratovskaya blast). This might dueto the cold spell during this period and the harvest of crops. Beforemid-November, most of the Volga region, south of Urals Region, andChelyabinskaya oblast (which is dominated by winter wheat) enjoyed above averageNDVI condition, while the Central Region presented an NDVI valley in November.These findings are also confirmed by the maximum VCI map (a, high values are darkgreen; lower values are yellow). In January, the north of the Southern Region—5.6percent of the country’s area and including Rostovskaya oblast, Krasnodarskiy kray,Stavropolskiy kray, Kalmykiya Rep., and the north of Volgogradskaya oblast—presentan NDVI peak.
