The MATUCPTDT or tavgU_3d_tdt_Cp data product is the MERRA Data Assimilation System 3-Dimensional temperature tendencies that is time averaged on pressure levels at a reduced resolution. It is a history file that is 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 3-dimensional fields that do not vary during the reanalysis.
The data are on the GEOS-5 native 288 x 144 grid with 1.25° longitude x 1.25° latitude resolution. The pressure-level data will be output in 42 pressure levels. Data are archived in the HDF-EOS (Grid) format, based on HDF4.
