  • Global Data Base of Monthly Mean Cloud and Surface Properties

    https://cmr.earthdata.nasa.gov/search/concepts/C1214584387-SCIOPS.xml
    Description:

    Global monthly means were obtained from ISCCP C1 data, which is available every 3 hours at 2.5 degree equal area spatial resolution. The monthly mean maps were replicated to a 2.5 degree square grid (144 longitude boxes by 72 latitude boxes). Monthly means are provided for Cloud Amount (CLDAMT), Cloud Top Temperature (CLDTMP), Cloud Top Pressure (CLDPRS), Cloud Optical Thickness (OPTTHK), Surface Temperature (SRFTMP), and Surface Reflectance (SRFRFL).

  • International Satellite Cloud Climatology Project (ISCCP) Stage B3 Reduced Radiances in Native Format

    https://cmr.earthdata.nasa.gov/search/concepts/C7994310-LARC_ASDC.xml
    Description:

    The ISCCP_B3_NAT data is the International Satellite Cloud Climatology Project (ISCCP) Stage B3 Reduced Radiances in Native Format data product. This is the original radiance data, sampled to 30 Km and 3-hour spacing. Data collection for this product is complete and was collected using several instruments on multiple platforms, please see the instrument and platform list of this record for a comprehensive list. The normalization of all radiances to a standard calibration made these data a globally uniform set of measurements that can be used for detailed cloud process studies. ISCCP was the first project of the World Climate Research Program (WCRP) and was established in 1982 (WMO-35 1982, Schiffer and Rossow 1983) to: produce a global, reduced resolution, calibrated and normalized radiance data set containing basic information on the properties of the atmosphere from which cloud parameters can be derived; stimulate and coordinate basic research on techniques for inferring the physical properties of clouds from the condensed radiance data set and to apply the resulting algorithms to derive and validate a global cloud climatology for improving the parameterization of clouds in climate models; and promote research using ISCCP data that contributes to improved understanding of the Earth's radiation budget and hydrological cycle. Since 1983 an international group of institutions has collected and analyzed satellite radiance measurements from up to five geostationary and two polar orbiting satellites to infer the global distribution of cloud properties and their diurnal, seasonal and inter-annual variations. The primary focus of the first phase of the project (1983-1995) was the elucidation of the role of clouds in the radiation budget (top of the atmosphere and surface). In the second phase of the project (1995 onwards) the analysis also concerns improving understanding of clouds in the global hydrological cycle. ISCCP analysis combined satellite-measured radiances (Stage B3 data, Schiffer and Rossow 1985), Rossow et al. 1987) with the TOVS atmospheric temperature-humidity and ice/snow correlative data sets to obtain information about clouds and the surface. The analysis method first determined the presence of absence of clouds in each individual image pixel and retrieves the radiometric properties of the cloud for each cloudy pixel and of the surface for each clear pixel. The pixel analysis is performed separately for each satellite radiance data set and the results reported in the Stage DX data product, which has a nominal resolution of 30 km and 3 hours. The Stage D1 product is produced by summarizing the pixel-level results every 3 hours on an equal-area map with 280 km resolution and merging the results from separate satellites with the atmospheric and ice/snow data sets to produce global coverage at each time. The Stage D2 data product is produced by averaging the Stage D1 data over each month, first at each of the eight three hour time intervals and then over all time intervals.

  • Remotely Accessible Near-Real Time Imagery from Polar Orbiting and Geostationary Satellites

    https://cmr.earthdata.nasa.gov/search/concepts/C1214584531-SCIOPS.xml
    Description:

    Satellite receiving systems for the NOAA polar orbiting satellites and the Japanese GMS geostationary satellite have been installed in Honolulu. Visible and infrared images are available. The systems are controlled by workstations connected to the Internet. The emphasis has been on real-time processing, generation of scientifically useful products and worldwide Internet access of subsets of data, although the full raw data is archived on 8 mm tapes as well. The images are automatically calibrated, ground-located and registered to a set of 'tiles' covering areas of interest. As of April 1993 these consist of the following: the Hawaiian EEZ (NOAA-AVHRR), the JGOFS/EQPAC area (NOAA-AVHRR), the CEPEX area (NOAA-AVHRR), the TOGA-COARE area (GMS-VISSR) and a full-globe image (GMS). The tiles can be accessed by anonymous ftp. Distribution of images by electronic mail through INMARSAT to ships at sea is also possible. The processed images are typically available within less than one hour of the data acquisition.

  • Surface Radiation Budget (SRB) Release 3.0 Shortwave 3 hourly monthly UTC data in netcdf format

    https://cmr.earthdata.nasa.gov/search/concepts/C2184128386-LARC_ASDC.xml
    Description:

    The data set contains monthly average/3-hourly (also calleddiurnally-resolved monthly average or just 'diurnal' for brevity) global fieldsof 11 shortwave (SW) surface radiative parameters derived with the Shortwavealgorithm of the NASA World Climate Research Programme /Global Energy andWater-Cycle Experiment (WCRP/GEWEX) Surface Radiation Budget (SRB) Project.The data is generated using the Pinker/Laszlo shortwave algorithm (R.T. Pinkerand I. Laszlo, 1992: Modeling Surface Solar Irradiance for SatelliteApplications on a Global Scale, J. Appl. Met., 31, 194-211).These parameters were derived originally on a 3-hourly temporal resolution(i.e., a global instantaneous gridded field every 3 hours), at UT hours 00, 03,06, 09, 12, 15, 18, and 21 for every day of the month. The 3-hourly values wereused to compute monthly averages separately for each of the 8 UT hours. Thecurrent version of the data is identified as Release 3.0.
