VISSR/GOES-3 Infrared Imagery on 70mm Film V001 (VISSRGOES3IMIR) at GES DISC

VISSRGOES3IMIR is the Visible Infrared Spin-Scan Radiometer (VISSR) Infrared Imagery on 70mm Film data product from the third Geostationary Operational Environmental Satellite (GOES-3). This set of IR imagery (10.5 to 12.5 micrometer) was originally produced on commercial image-generation equipment from digital tapes and was made available on 70-mm film, from which they were later scanned to digital TIFF image files. Each TIFF scan contains 2 or 3 pictures, and there are several hundred scans from an original 70 mm film roll which are combined into a ZIP file. Each picture contains a title on the top boundary and a 33-level gray scale on the right boundary that represents brightness temperatures. It may have a combination of the following options: 1) contrast enhancement, 2) image sectorization, and 3) 1/16-size imagery. The maximum effective size covers 500 sq km, represented by 4000 by 3904 pixels. Each element has a maximum resolution of 3.7 km. The title contains the satellite identification, picture number, picture type, coordinate numbers of the top left pixel relative to the visible sensor, start time of sectorized image, and pixel scaling and sector size identification. The GOES-3 satellite was parked over the equator at longitude 135W from 1978 through 1981 viewing the hemisphere below the satellite. The VISSR experiment was operated by the NOAA National Environmental Satellite Data and Information Service (NESDIS), as well as scientists from NASA Goddard Space Flight Center. This product was previously available from the NSSDC with the identifier ESAD-00105 (old ID 75-100A-01C).

VIIRS/JPSS2 Moderate Resolution 6-Min L1B Swath 750m NRT

The Near Real Time (NRT) VIIRS/JPSS2 Moderate Resolution 6-Min L1B Swath 750m, short-name VJ202MOD_NRT is the Joint Polar-orbiting Satellite System-2 (JPSS-2/NOAA-21; referred to hereafter as J2) platform-derived NASA VIIRS L1B calibrated radiances product that comprises of sixteen moderate-resolution or M-bands with a spatial resolution of 750-meters at nadir. These M-bands comprise eleven reflective solar bands (RSB) and five thermal emissive bands (TEB). Each of the M-bands has 16 detectors in the along-track direction with 16 rows of pixels per scan that provide a 750-m resolution. Ranging in wavelengths from 0.402 µm to 12.49 µm, the M-bands are sensitive to visible, near-, shortwave-, mediumwave-, and longwave-infrared wavelengths. Derived from the NASA VIIRS L1A raw radiances, this product includes calibrated and geolocated radiance and reflectance data, quality flags, and granule- and collection-level metadata. In contrast to a MODIS L1B product, which temporally spans 5 minutes, the VIIRS L1B calibrated radiances product contains a nominal temporal duration of 6 minutes. The image dimensions of the 750-m swath product measure 3232 lines by 3200 pixels. The J2 VIIRS radiometric calibration Level-1B reprocessing includes a few calibration updates for the reflective solar bands (RSB), but no significant changes for the day-night band (DNB) or thermal emissive bands (TEB).

Very Long Baseline Interferometry (VLBI) Level 1A correlator (SWIN) output from NASA CDDIS

SWIN files contain the VLBI fringe visibilities of an observing session (24 hours long or 1 hour long). The files are created by the International VLBI Service for Geodesy and Astrometry (IVS) correlation centers and constitute the raw output of the Distributed FX-style (DiFX) software correlator running on a Swinburne supercomputer. These data form the basis for the fringe fitting process and can also be used to make source maps of the observed quasars.

Vegetation Index and Phenology (VIP) Phenology EVI-2 Yearly Global 0.05Deg CMG V004

The NASA Making Earth System Data Records for Use in Research Environments ([MEaSUREs](https://earthdata.nasa.gov/about/competitive-programs/measures)) Vegetation Index and Phenology (VIP) global datasets were created using surface reflectance data from the Advanced Very High Resolution Radiometer (AVHRR) N07, N09, N11, and N14 datasets (1981 – 1999) and Moderate Resolution Imaging Spectroradiometer (MODIS)/Terra MOD09 surface reflectance data (2000 - 2014). The VIP Vegetation Index (VI) product was developed to provide consistent measurements of the Normalized Difference Vegetation Index (NDVI) and modified Enhanced Vegetation Index (EVI2) spanning more than 30 years of data from multiple sensors. The EVI2 is a backward extension of AVHRR. Vegetation indices such as NDVI and EVI2 are useful for assessing the biophysical properties of the land surface, and are used to characterize vegetation phenology. Phenology tracks the seasonal life cycle of vegetation, and provides information on the biotic response to environmental changes. The VIPPHEN data product is provided globally at 0.05 degree (5600 meters (m)) spatial resolution in geographic (Lat/Lon) grid format. The data are stored in Hierarchical Data Format-Earth Observing System (HDF-EOS) file format. The VIPPHEN phenology product contains 26 Science Datasets (SDS) which include phenological metrics such as the start, peak, and end of season as well as the rate of greening and senescence. The product also provides the maximum, average, and background calculated VIs. The VIPPHEN SDS are based on the daily VIP product series and are calculated using a 3-year moving window average to smooth out noise in the data. A reliability SDS is included to provide context on the quality of the input data.

VNP02MOD | VIIRS/NPP Moderate Resolution 6-Min L1B Swath 750 m

The VNP02MOD | VIIRS/NPP Moderate Resolution 6-Min L1B Swath 750m, short-name VNP02MOD contains the derived line-of-sight (LOS) vectors for each of the 750-m moderate-resolution, or M-bands. The geolocation algorithm uses a number of inputs that include an Earth ellipsoid, geoid, and a digital terrain model along with the SNPP platform’s ephemeris and attitude data, and knowledge of the VIIRS sensor and satellite geometry. It produces geodetic coordinates (latitude and longitude), and related parameters for each VIIRS L1 pixel. The VNP03MOD product includes geodetic latitude, longitude, surface height above the geoid, solar zenith and azimuth angles, sensor zenith and azimuth angles, land/water mask, and quality flag for every pixel location.
