NASA DC-8 EARTH AIRSAR RESAMPLED RADAR IMAGES V1.0

AIRSAR is the Jet Propulsion Laboratory's airborne polarimetric SAR that operates at C (5.66 cm), L (23.98 cm), and P (68.13 cm) wavelengths in a polarimetric mode (Zebker et al., 1987). AIRSAR acquires data that can be processed to backscatter image formats with range and azimuth resolutions of approximately 20 meters. The pixel values are expressed in radar backscatter cross section as 32-bit numbers. The cross section is the area of a half sphere that would scatter the amount of power received by the antenna.

PVO VENUS MAG CALIBRATED P-SENSOR HIGH RES V1.0

This dataset contains full resolution
magnetometer data from the Pioneer Venus Orbiter spacecraft beginning with
orbit 3602 (Oct 16, 1988) and continuing until the orbiter was lost in the
Venusian atmosphere (orbit 5055, Oct 7, 1992). The dataset differs from the
high resolution magnetometer dataset from theprevious orbits due to an
anomaly in the multiplexor that controlled the sampling of the magnetometer
sensors. During orbit 3602, and for the remainder of the mission, the
spacecraft downlink contained magnetometer data from only the P sensor. The
P sensor is the sensor which is aligned with the spacecraft spin axis,
nominally in the direction of the ecliptic normal.

SPECTRA OF V-TYPE CANDIDATES FROM THE SDSS MOC V1.0

These data are the results of a spectroscopic survey designed to target and detect asteroids whose photometric colors are similar to those of Vesta family members and thus may be considered as candidates for having a basaltic composition. The colors of these candidates were measured as part of the 3rd release of the Sloan Digital Sky Survey Moving Object Catalog (Ivezic et al. 2001) [IVEZICETAL2001]. These spectra were obtained with two visible wavelength instruments: the Echellete Spectrograph and Imager (ESI, Sheinis et al. 2002) [SHEINISETAL2002] on Keck II and the Supernova Integral Field Spectrograph (SNIFS, Lantz et al. 2004) [LANTZETAL2004] at the University of Hawaii 2.2m telescope.

Sentinel-5P TROPOMI SNPP cloud product band 7 (SWIR detector) 1-Orbit L2 7km x 7km V1 (S5P_L2__NP_BD7) at GES DISC

Starting from August 6th in 2019, Sentinel-5P TROPOMI along-track high spatial resolution (~5.5km at nadir) has been implemented.
For data after August 6th of 2019, please check S5P_L2__NP_BD7 data collection.

The Copernicus Sentinel-5 Precursor (Sentinel-5P or S5P) satellite mission is one of the European Space Agency's (ESA) new mission family - Sentinels, and it is a joint initiative between the Kingdom of the Netherlands and the ESA. The sole payload on Sentinel-5P is the TROPOspheric Monitoring Instrument (TROPOMI), which is a nadir-viewing 108 degree Field-of-View push-broom grating hyperspectral spectrometer, covering the wavelength of ultraviolet-visible (UV-VIS, 270nm to 495nm), near infrared (NIR, 675nm to 775nm), and shortwave infrared (SWIR, 2305nm-2385nm). Sentinel-5P is the first of the Atmospheric Composition Sentinels and is expected to provide measurements of ozone, NO2, SO2, CH4, CO, formaldehyde, aerosols and cloud at high spatial, temporal and spectral resolutions.

Copernicus Sentinel-5P is flying in a loose formation with U.S. Suomi National Polar-orbiting Partnership (SNPP) so that S5P is able to utilize the high spatial resolution capability of the Visible Infrared Imager Radiometer Suite (VIIRS) instrument. S5P_L2_NP_BDx product contains VIIRS cloud information for each S5P across-track observation in a given band (i.e. band 3, band 6 and band 7). In addition to the nominal filed-of-view (FOV), the S5P_NPPC products are also generated for three scaled FOVs both in along and across-track directions to account for the presence of cloud covering a more extended area than the nominal FOV. The main output of S5P_L2_NP_BDx are the number of VIIRS pixels classified as confidently cloudy, probably cloudy, probably clear, and confidently clear; and the VIIRS sun-normalized radiance information in band M7, M9, and M11 such as mean, standard deviation, as well as number of valid radiance contributions.
