During the reporting period, single season crops (maize, wheat, and soybean) were grown in Inner Mongolia. Overall, RAIN was close to the 15YA. TEMP (+0.6°C) was slightly above average, while RADPAR was slightly below average (-1%). BIOMASS (-5%) was also below 5YA. The temporal distribution for these indicators was very uneven. Precipitation was insufficient in May and June, which may have a negative impact on the rain-fed crops. As illustrated in the crop development graph from April to July, almost all cropped areas displayed consistently below-average NDVI, and more than 70% of the area had a sustained decrease in northern Hebei, central and eastern Inner Mongolia. This is confirmed by VCIx values being lower than 0.8 in these areas, where the biomass accumulation potential (BIOMSS) was also well below average. In July, crop conditions have recovered for most areas due to the increasing precipitation, but still below average. The fraction of cropped arable land (CALF) was 95%, and VCIx was 0.79. Crop conditions were slightly below average during the reporting period, which is consistent with the agricultural production situation index (0.94). The season's final outcome was expected to be below average.
