Retrieved parameters include: particle size, water content, water path, particle concentration, and optical depth for all-ice, all-liquid, mixed-phase, and precipitating cloud types. The companion radar and radiometer files on which these retrievals are based are also available in the NCAR-EOL data archive.
These data are daily averaged 1 m binned profiles of thermal microstructure dissipation rate, chi, and the corresponding temperature, salinity and potential density to a depth of 150 m.

This data set contains NOAA-14 3.7-micron band images (GIF) provided by SSEC at the University of Wisconsin. Images are available at 2200 UTC. Images also have latitude and longitude and ice camp position as overlays.
Tower, 5-level Daily Average measurements plus radiometer and surface data at Met City (ASFG). Version 1.0E. Andreas, C. Fairall, P. Guest & O. Persson
This dataset contains processed data from the flux group tower at "Met City" in the SHEBA ice camp. This dataset contains data from all 5 levels on the tower as well as the radiometer and surface measurements (including the Barnes, GE and the two thermistors). The tower data include sensible heat flux and momentum flux as well as the relative humidity (RH), wind speed and temperature data. This dataset also includes variances, structure functions etc....
The presence of particulates in the snow cover and at the ice surface can decrease the spectral albedo of the system at visible wavelengths where absorption by ice and water is small. Because of this, we were concerned that the release and local deposition of soot particles from fuel burned onboard the ship could impact both albedos and melt rates. For additional documentation, start with the soot.htm file contained in the zip file html-metadata.zip.
The Depolarization and Backscatter - Unattended Lidar (DABUL) is a pulsed laser-radar operating at 523 nm wavelength. Range resolution is 30 m, and time resolution is as short as 1 s. This dataset contains two final products: Lidar returned-power netcdf data files, and Linear depolarization ratio netcdf data files. All of the final products have been averaged for 10 seconds.
