This analysis covers the late stages of sugar beets and maize (harvest completed in November, according to HGCA crop updates) and the early vegetative stages of wheat and rapeseed. The CropWatch environmental indices show an increase in temperature and PAR accumulation (1.7℃ and 2 percent respectively), and a decrease in rainfall and biomass (-20 percent and -5 percent respectively) compared with the last five-year average. These observations are consistent with the records in the JRC/MARS bulletin that Poland experienced a positive thermal anomaly and drier han usual weather condition, which may cause a slow down or delay in thecrop hardening process. This slow-down process is well captured by the NDVI profiles (e) with an overall decreasing trend of national NDVI values (althoughabove the five-year average from December to early January). The sharp drop inlate January in both figures (e) and (c) might be due to the cold air flow ove rPoland around January 15, as reported by JRC/MARS. The maximum VCI map indicatesthat the best crop condition (a, in dark green) in this period prevails in the southwest (Wielkopolskie, Dolnoslaskie) and southeast (Mazowieckie, Lubeiskie)of the country, while crop condition in the central and northern region is lessfavorable, which agrees well with the pattern from the NDVI cluster (b). Figure(d) shows that, compared with the recent five years, the spatial distributionof biomass over the reporting period present a patterns increasing from southwest to northeast.
