TES/Aura L2 Atmospheric Temperatures Nadir V007

TL2ATMTN_7 is the Tropospheric Emission Spectrometer (TES)/Aura Level 2 Atmospheric Temperatures Nadir Version 7 data product. TES was an instrument aboard NASA's Aura satellite and was launched from California on July 15, 2004. Data collection for TES is complete. TES Level 2 data contains retrieved species (or temperature) profiles at the observation targets and the estimated errors. The geolocation, quality, and other data (e.g., surface characteristics for nadir observations) were also provided. L2 modeled spectra were evaluated using radiative transfer modeling algorithms. The process, referred to as retrieval, compared observed spectra to the modeled spectra and iteratively updated the atmospheric parameters. L2 standard product files included information for one molecular species (or temperature) for an entire global survey or special observation run. A global survey consisted of a maximum of 16 consecutive orbits. Nadir and limb observations were added to separate L2 files, and a single ancillary file was composed of data that are common to both nadir and limb files. A Nadir sequence within the TES Global Survey was a fixed number of observations within an orbit for a Global Survey. Prior to April 24, 2005, it consisted of two low resolution scans over the same ground locations. After April 24, 2005, Global Survey data consisted of three low resolution scans. The Nadir standard product consists of four files, where each file is composed of the Global Survey Nadir observations from one of four focal planes for a single orbit, i.e. 72 orbit sequences. The Global Survey Nadir observations only used a single set of filter mix. A Limb sequence within the TES Global Survey involved three high-resolution scans over the same limb locations. The Limb standard product consisted of four files, where each file was composed of the Global Survey Limb observations from one of four focal planes for a single orbit, i.e. 72 orbit sequences. The Global Survey Limb observations used a repeating sequence of filter wheel positions. Special Observations could only be scheduled during the 9 or 10 orbit gaps in the Global Surveys, and were conducted in any of three basic modes: stare, transect, step-and-stare. The mode used depended on the science requirement. A Global Survey consisted of observations along 16 consecutive orbits at the start of a two day cycle, over which 4,608 retrievals were performed (1,152 nadir retrievals and 1,152 retrievals in time ordered sequence for each limb observation). Each observation was the input for retrievals of species Volume Mixing Ratios (VMR), temperature profiles, surface temperature, and other data parameters with associated pressure levels, precision, total error, vertical resolution, total column density, and other diagnostic quantities. Each TES Level 2 standard product reported information in a swath format conforming to the HDF-EOS Aura File Format Guidelines. Each Swath object was bounded by the number of observations in a global survey and a predefined set of pressure levels, representing slices through the atmosphere. Each standard product could have had a variable number of observations depending upon the Global Survey configuration and whether averaging was employed. Also, missing or bad retrievals were not reported. Each limb observation Limb 1, Limb 2 and Limb 3, were processed independently. Thus, each limb standard product consisted of three sets where each set consisted of 1,152 observations. For TES, the swath object represented one of these sets. Thus, each limb standard product consisted of three swath objects, one for each observation, Limb 1, Limb 2, and Limb 3. The organization of data within the Swath object was based on a superset of Upper Atmosphere Research Satellite (UARS) pressure levels used to report concentrations of trace atmospheric gases. The reporting grid was the same pressure grid used for modeling. There were 67 reporting levels from 1211.53 hPa, which allow

It also contains quality flags, pixel classification information and meteorological annotations. Based on components activated by configuration which are not part of the operational production baseline, the S3A_SL_1_RBT may contain 77 or 111 files. Out of the these files, 22 or 34 files contain the actual measurements, where the other 54 or 76 files contain the annotations data.

Sentinel-3B OLCI Top of Atmosphere (TOA) Radiances at Full Resolution (FR) Data, version 1

The Ocean and Land Colour Instrument (OLCI) is the successor to ENVISAT's Medium Resolution Imaging Spectrometer (MERIS) having additional spectral channels, different camera arrangements and simplified on-board processing. The OLCI is a push-broom instrument with five camera modules sharing the field of view. The field of view of the five cameras is arranged in a fan-shaped configuration in the vertical plane, perpendicular to the platform velocity. Each camera has an individual field of view of 14.2° and a 0.6° overlap with its neighbors. The whole field of view is shifted across track by 12.6 degrees away from the sun to minimize the impact of sun glint. OLCI is equipped with on-board calibration hardware based on sun diffusers. There are three sun diffusers--two 'white' diffusers dedicated to radiometric calibration and one dedicated to spectral calibration, with spectral reflectance features. The native resolution is approximately 300m, referred to as Full Resolution(FR). A Reduced Resolution (RR) processing mode provides Level-1B data at sampling rates decreased by a factor of four in both spatial dimensions resulting to resolution of approximately 1.2 km.

VO1/VO2 MARS ATMOSPHERIC WATER DETECTOR 4 V1.0

This data set consists of the raster-averaged radiant intensities and associated data parameters produced from data acquired by the Mars Atmospheric Water Detectors (MAWD) onboard the Viking Orbiters. The basic observations give temporal coverage spanning just over two martian years and variable, but extensive, spatial coverage of the planet. MAWD was a five-channel grating spectrometer measuring solar radiation reflected from the surface and atmosphere of Mars in and out of water vapor bands in the 1.4 micrometer spectral interval. The data set described here contains the solar reflected radiant intensities (i.e., radiances) measured by MAWD, derived water vapor column abundances, a derived '1.4-micrometer brightness', and ancillary data (e.g., viewing geometry, surface elevation and air mass). Column water vapor abundances were derived by comparing the reflected radiant intensities in three water vapor absorption bands to radiant intensities in the two interspersed continua observed air mass and then normalized by the air mass to obtain a vertical column abundance. A basic description of the instrument, its observational modes and its derived data products is given in [FARMER_ETAL_1977]. A description of the global and seasonal variation of water vapor on Mars, based on the complete MAWD observational record, is given in [JAKOSKY_FARMER_1982]. This data set was generated from the raster-level data base constructed during the Viking Mission on the original data processing system (IRPS: Infrared Processing System) by the MAWD Science Team, led by C. B. Farmer, JPL. Together with the instantaneous field of view (IFOV) radiances and geometry, the raster-level radiances, associated water column abundances and ancillary data have been archived at the NSSDC (NSSDC id 75-075A-03A, 75-083A-03A). Data from the final phase of the VO-1 mission were added, supervised by R. Zurek, JPL. Eventually, the data set was restructured, additional quality flags were introduced, and a second estimate of the water vapor column abundance (WFAPT, termed COLUMN_H2O_A in the data set) was added [by R. Zurek, JPL [JAKOSKY_ETAL_1988].]. The data base was restructured, while preserving key unique parameters, into a consistent format with the Viking Orbiter Infrared Thermal Mapper (IRTM) data [R. Mehlman, R. Zurek]. Both the MAWD and IRTM data sets were then accessible with the XXFUNC package. Further quality checking of the MAWD data was carried out by B. Jakosky, U. Colorado.
