Revision as of 15:51, 3 August 2015
MERRA2 is a new NASA/GMAO reanalysis product. It has a horizontal resolution of 0.5° lat x 0.625° lon x 72 vertical levels. The horizontal resolution is 2x coarser than the GMAO "forward processing" product (which we refer to as GEOS-FP). But MERRA2 uses the identical vertical grid as the GEOS-5#GEOS-5, MERRA, and the "GEOS-FP" data products used by GEOS-Chem.
NOTE: GEOS-Chem only uses a subset of the entire MERRA2 data archive. On this page we list the MERRA2 met fields that we archive for use with GEOS-Chem.
As of August 2015, we have not finalized this list of MERRA2 met fields that we will archive for GEOS-Chem. If your research requires additional fields not listed below, please contact the GEOS-Chem Support Team.
Constant fields
- These data will be timestamped 2015/01/01 at 00:00 GMT for convenience.
- These are time-invariant constant fields, which will have the following filenames:
- MERRA2.20110101.CN.05x0625.CH.nc (Native resolution nested CH grid)
- MERRA2.20110101.CN.05x0625.EU.nc (Native resolution nested EU grid)
- MERRA2.20110101.CN.05x0625.NA.nc (Native resolution nested NA grid)
- MERRA2.20110101.CN.05x0625.NA.nc (Native resolution nested SE grid)
- MERRA2.20110101.CN.2x25.nc (2° x 2.5° global grid)
- MERRA2.20110101.CN.4x5.nc (4° x 5° global grid)
- The Collection indicates the MERRA2 raw data files in which each field may be found.
- One MERRA2 raw data file is created for each day of data.
- Therefore, the CN data fields listed below will be contained in a single MERRA2 raw data file.
Field | Units | Collection | Description | Notes | Where used in GEOS-Chem? |
---|---|---|---|---|---|
FRLAKE | 1 | const_2d_asm_Nx | Fraction of lake type in grid box |
| |
FRLAND | 1 | const_2d_asm_Nx | Fraction of land type in grid box |
| |
FRLANDIC(E) | 1 | const_2d_asm_Nx | Fraction of land ice type in grid box |
|
|
FROCEAN | 1 | const_2d_asm_Nx | Fraction of ocean in grid box |
| |
PHIS | m2 s-2 | const_2d_asm_Nx | Surface geopotential |

A1 fields
- These are 1-hr time-averaged fields, which will have the following filenames:
- MERRA2.YYYYMMDD.A1.05x0625.CH.nc (Native resolution nested CH grid)
- MERRA2.YYYYMMDD.A1.05x0625.EU.nc (Native resolution nested EU grid)
- MERRA2.YYYYMMDD.A1.05x0625.NA.nc (Native resolution nested NA grid)
- MERRA2.YYYYMMDD.A1.025x03125.SE.nc (Native resolution nested SE grid)
- MERRA2.YYYYMMDD.A1.2x25.nc (2° x 2.5° global grid)
- MERRA2.YYYYMMDD.A1.4x5.nc (4° x 5° global grid)
- All A1 fields are 2-dimensional (lon,lat)
- Timestamps (i.e. center of averaging period): 00:30, 01:30, 02:30 ... 23:30 GMT
- The Collection indicates the GEOS-FP raw data files in which each field may be found.
- One MERRA2 raw data file is created for each new day of data
- Therefore, the A1 data fields listed below will be contained in a single MERRA2 raw data file.
