The project involves a sophisticated data assimilation system (based on the operational set-up as of December 2018) incorporating development results from the operational NWP system and sea surface temperature analysis achieved since JRA-55 (based on the operational set-up as of December 2009). New datasets of past observations are also assimilated, including rescued historical observations and reprocessed satellite data supplied by meteorological and satellite centers worldwide. Many of the deficiencies of JRA-55 are alleviated in JRA-3Q, providing a high-quality homogeneous reanalysis dataset that covers the previous 75 years.","jma_data_url":"https:\/\/jra.kishou.go.jp\/JRA-3Q\/index_en.html","jma_data_group":"Isobaric forecast fields (fcst_p)","jma_data_original_format":"WMO GRIB edition 2","jma_data_original_grid":"Reduced (thinned) N240 global Gaussian grid: variable number of longitudes x 480 latitudes, 960 grid points at latitudes 0.18730N and 0.18730S, 48 grid points at latitudes 89.71324N and 89.71324S.
