◎ China's First-Generation Global Land Reanalysis Products (CRA-40/Land)- Daily Products (Atmospheric Driven Fusion Products)
The National Meteorological Information Center has established a global land surface reanalysis system in China based on core technologies such as set assimilation algorithm, multi-source fusion method, Noah 3.3 land surface model, and surface parameter optimization. The model has a horizontal resolution of Gaussian grid 1152 × 576 (about 34 km), a time resolution of 3 hours per hour, and is vertically divided into 4 layers (0-0.1, 0.1-0.4, 0.4-1.0, 1.0-2.0 m). This includes two types of datasets: atmospheric driven fusion products (2m temperature, 2m specific humidity, 10m U wind, 10m V wind, precipitation) and land surface products (including about 30 land surface elements such as surface temperature, soil temperature, soil humidity, flux, and snow cover). The inspection and evaluation show that the product data quality is reliable and the application effect is good.
