This collection consists of  analyzed meteorological fields at 42 pressure levels, such as  temperature, wind components, specific humidity, ozone mixing ratio, and geopotential height.  The information on the pressure levels can be found in the section 4.2 of the MERRA-2 File Specification document.  The collection also includes certain quadratic information (such as the variance and covariance of certain parameters).  \n\nMERRA-2 is the latest version of global atmospheric reanalysis for the satellite era produced by NASA Global Modeling and Assimilation Office (GMAO) using the Goddard Earth Observing System Model (GEOS) version 5.12.4.  The dataset covers the period of 1980-present with the latency of ~3 weeks after the end of a month. \n\nData Reprocessing:  Please check \u201cRecords of MERRA-2 Data Reprocessing and Service Changes\u201d linked from the \u201cDocumentation\u201d tab on this page.  Note that a reprocessed data filename is different from the original file.\n\nMERRA-2 Mailing List: Sign up to receive information on reprocessing of data, changing of tools and services, as well as data announcements from GMAO. Contact the GES DISC Help Desk (gsfc-dl-help-disc@mail.nasa.gov) to be added to the list.\n\nQuestions: If you have a question, please read \"MERRA-2 File Specification Document\",  \u201cMERRA-2 Data Access \u2013 Quick Start Guide\u201d, and FAQs linked from the \u201dDocumentation\u201d tab on this page.
