MAI3NECHM
The MAI3NECHM or inst3_3d_chm_Ne data product is the MERRA Data Assimilation System Chemistry 3-Dimensional chemistry on layer Edges that is time averaged, 3D model levels, at native resolution. It is a history file that is intended for forcing off-line chemistry/aerosol models with the results of the reanalysis. Like other histories, they are produced from the GCM during the corrector segment of the IAU cycle. All collections from this group are at reduced horizontal resolution. MERRA, or the Modern Era Retrospective-analysis for Research and Application, is a NASA reanalysis for the satellite era (30 years 1979-current) using the Goddard Earth Observing System Data Assimilation System Version 5 (GEOS-5 DAS).This data product contains fields that do not vary during the reanalysis. The data are on the GEOS-5 native 540 x 361 grid with 0.667 degree longitude x 0.5 degree latitude resolution. The files are compacted into a single daily file with the times: 1:30, 4:30, 7:30, 10:30, 13:30, 16:30, 19:30, 22:30 GMT. Data are archived in the HDF-EOS2 (Grid) format, based on HDF4.Sign Up for the MERRA-2 Mailing ListSign up for the MERRA-2 listserv to receive announcements on the latest data information, tools and services that become available, data announcements from GMAO and more!
