CERES Clouds and Computed Flux Profile Processing Data Sets |
|
CERES Clouds and Computed Flux Profile uses radiative transfer code to model in atmosphere as well as surface fluxes. Treatment of clouds using VIRS/MODIS retrieved cloud properties, multi-constituent aerosols with satellite retrieved optical depths, scene and spectrally dependent surface boundary conditions. Time-space averaging using geostationary based cloud properties and grid scale radiative transfer.

|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
The Clouds and Radiative Swath (CRS) product contains one hour of instantaneous
Clouds and the Earth's Radiant Energy System (CERES) data for a single scanner
instrument. The CRS contains all of the CERES SSF product data. For each CERES
FOV on the SSF, the CRS also contains vertical flux profiles evaluated at
five levels in the atmosphere: the surface, 500 hPa, 200 hPa, 70 hPa, and
the TOA. After an initial pass through the radiative transfer model, the input
parameters to the model are adjusted and a constrained pass through the model
is made for both clear sky and total sky. If the FOV is overcast, clear sky
fluxes are still calculated.

| Monthly Gridded Radiative Fluxes and Clouds (FSW) | ||||||||||||||||||
The Monthly Gridded Radiative Fluxes and Clouds (FSW) archival data product
contains hourly single scanner flux and cloud parameters averaged over 1.0-degree
regions. Input to the FSW Subsystem is the Clouds and Radiative Swath (CRS)
archival data product. Each FSW covers a single month swath from a single
CERES instrument mounted on one satellite. The product is written in HDF and
contains metadata as well as gridded science data. The HDF product for TRMM
consists of eight files, each containing data for ten 1.0-degree equal-angle
zones. The HDF product for Terra and Aqua consists of 60 files, each containing
data for three 1.0-degree equal-angle zones. Each record contains spatially
averaged data for an individual region.

| Synoptic Radiative Fluxes and Clouds (SYN) | ||||||||||||||||||
The Synoptic Radiative Fluxes and Clouds (SYN) product contains a day of
space and time averaged Clouds and the Earth's Radiant Energy System (CERES)
data for a single scanner instrument. The 1-degree regional flux at the hour
of observation from the CERES FSW product and concurrent diurnal data from
geostationary satellites are used to estimate the regional flux at 3-hour GMT
based intervals. Also at 3-hour intervals are estimates of the adjusted
(tuned) fluxes at the five atmospheric levels as defined by the CERES CRS
product for both clear-sky and totalsky scenes, estimates of the average
cloud parameters in four cloud height categories, and averaged cloud
parameters.

| Monthly Regional Radiative and Clouds (AVG) | ||||||||||||||||||
The monthly Regional Radiative and Clouds (AVG) product contains monthly
and monthly hourly (3-hour) averages of the Synoptic Radiative Fluxes and
Clouds (SYN) product. This product is the CERES equivalent of the monthly
regional averages in the ERBE ES-4 product of the CERES untuned and tuned
radiative transfer modeled fluxes. This product is written in HDF_EOS and
contains meta data as well as gridded science data.
|
||||||||||||||||||
| Monthly Zonal and Global Radiative Fluxes and Clouds (ZAVG) | ||||||||||||||||||
The Monthly Zonal and Global Radiative Fluxes and Clouds (ZAVG) product
are the zonal and global averages of the monthly Regional Radiative and
Clouds (AVG) product. This product is the CERES equivalent of the zonal and
global averages in the ERBE ES-4 product of the CERES untuned and tuned
radiative transfer modeled fluxes. This product is written in HDF_EOS and
contains meta data as well as gridded science data.
