52 COLOR ASTEROID SURVEY V1.0

The observations were made using a double CVF (circularly variable filter). The short wavelength portion of the CVF covered the octave from 0.8 to 1.6 microns with 3 percent resolution, while the long wavelength portion covered 1.5 to 2.6 microns with 5 percent resolution. There is some overlap in the spectral coverage between 1.5 and 1.6 microns, which is evident as a discontinuity in the wavelengths after the first 32 values, which were obtained with the short wavelength portion, while the remaining 20 values were obtained with the long wavelength portion.

MODIS/Aqua Clouds 1km and 5km 5-Min L2 Narrow Swath Subset along CloudSat V002 (MAC06S0) at GES DISC

This is the narrow-swath MODIS/Aqua subset along CloudSat field of view track. The goal of the narrow-swath subset is to select and return MODIS data that are within +-5 km across the CloudSat track. I.e. the resultant MODIS subset swath is sought to be about 10 km cross-track. However, the original MYD06_L2 has data of 5- and 1-km pixels. Thus, MAC06S0 cross-track width is 3- and 11-pixels, depending on the parameter, and the resultant swath is about 15- and 10-km, correspondingly. Along-track, all MODIS pixels from the original product are preserved.
      
In the standard product, the level-2 MODIS cloud product consists of cloud optical and physical parameters. These parameters are derived using remotely sensed infrared, visible and near infrared solar reflected radiances. MODIS infrared channel radiances are used to derive cloud top temperature, cloud top height, effective emissivity, cloud phase (ice vs. water, opaque vs. non-opaque), and cloud fraction under both daytime and  nighttime conditions. MODIS visible radiances are used to derive cloud optical thickness and effective particle radius and cloud shadow effects. Near infrared solar reflected radiance provides additional information in the retrieval of cloud particle phase (ice vs. water, clouds vs. snow). 

The shortname for this level-2 MODIS cloud product is MAC06S0.

YD06_L2 and the principal investigators for this product are MODIS scientists Dr. Bo-Cai Gao (gao@rsd.nrl.navy.mil) for cirrus cloud  detection; Dr. Paul Menzel (paulm@ssec.wisc.edu) for cloud top properties; and Dr. Michael King(king@climate.gsfc.nasa.gov) for cloud optical properties.

VEGA1 CRUISE MAGNETOMETER DATA

On Dec 15, 1984, the Vega spacecraft was launched to first flyby Venus at which time landers were released and then continue to a flyby of Halley. The magnetic field experiments MISCHA carried four fluxgate sensors, with three sensors mounted on a boom at the end of the solar panels and the fourth sensor mounted one meter closer. During the cruise phase, the TRASSA-1 mode of the instrument (1 vector/2.5 min) was used. The sensors were switched to the TRASSA-2 mode (1 vector/min) during the flyby which started roughly two days before the encounter. From 3 h before closest approach (CA) until 1 hour after CA, the HS-mode 1 vector/6s) and the DT-mode (1 vector/100ms) was used [DELVAETAL1991].

VEGA1 INFRARED SPECTROMETER IMAGING CHANNEL DATA V1.0

The IKS data from Vega-1 came in various forms. The initial submission from IKI by Dyachkov was in GROUP FITS (binary) for the 'imaging channel'. A separate submission came through the IHW Infrared Studies Discipline and also contained data presented in the FITS format (IHW keywords) for the two 'infrared channels'. In the former case, the three Pvalues carried information on the distance and two angles used to locate the position of the comet on the slit. The other simple keyword values marked only the date, mission, and experiment. The latter data, had not only 101 individual spectra for the 3-5 micron measurements but a composite 'final' 6-12 micron spectrum with associated 'figure 7' from the published results (COMBES, M. et al. 1988, Icarus, 76, 404). For these 101 spectra a cometo-centric distance was quoted rather than a time micron data. Using this information, the distance range was 270534.9 to 39273.22 km. From this comparison, it is inferred that the distance quoted in the IKI submission is also cometo-centric (31596.0 to 16092 km).

SnowEx20 Grand Mesa IOP Computed Tomography Snow Microstructure V001

This data set characterizes snow microstructure for 6 snow pits from the SnowEx 2020 Grand Mesa Intensive Observation Period (February 2020) using microcomputed tomography (micro-CT). Included with this data set are two- and three-dimensional microstructural analysis of DMP/DEP casted and un-casted snow samples, available as .xlsx and .txt file, and visual representations of the three-dimensional snow structure, available is .bmp image files. Containers of snow were collected at 6 snow pits in approximately 17 cm intervals. There were approximately 5-8 discrete containers per pit and each container had an ~2 cm overlap with the sample below. A 6-cm section of snow was dissected from each container of snow, which were analyzed in ~2 cm sub-sections. Each sub-section was scanned in three intervals using a micro-CT instrument. The three interval scans comprise multiple slices, and were combined into the reconstructed final scan used for calculating the snow microstructural data.

Indicators of Coastal Water Quality: Annual Chlorophyll-a Concentration 1998-2007

The Annual Chlorophyll-a Concentrations component of the Indicators of Coastal Water Quality Collection consists of gridded satellite measurements of chlorophyll-a concentrations (in nanogram/cubic meter) in a band extending between 10 and 100 km from the shoreline. Chlorophyll-a concentrations are derived from NASA's Sea-viewing Wide Field-of-view Sensor (SeaWiFS). The grids are based on annual composites of SeaWiFS satellite data provided by the SeaWiFS Project, NASA/Goddard Space Flight Center and GeoEye in the form of HDF files at a resolution of 5 arc-minutes (approximately 9 x 9 km at the equator). The source files are true-color images generated from sub-sampled, calibrated, Rayleigh-corrected level-2 data, which are derived from raw radiance counts by applying sensor calibration, atmospheric corrections, and bio-optical algorithms. To arrive at chlorophyll-a concentrations, radiance counts were converted using the conversion formula provided as part of the original data files. The gridding is done by the Columbia University Center for International Earth Science Information Network (CIESIN).
