The Global Radiation and Aerosol (GRAD) Group is part of NOAA's Earth System Research Laboratory (ESRL) in Boulder, CO. The GRAD Group is involved in observational and theoretical research of the Earth's surface and atmospheric radiation budgets. The group specializes in the investigation of climatically significant variations in long-term radiation and meteorological measurements made at diverse globally-remote sites and continental US sites.

This dataset from Remote Sensing Systems (RSS) consists of satellite swath-level brightness temperatures from the Special Sensor Microwave Imager/Sounder (SSMIS). SSMIS measures the natural microwave emission coming from the Earth’s surface in the spectral band from 19 to 85 GHz. There are roughly 15 orbits per day per satillite with a swath width of approximately 1400 km resulting in nearly global daily coverage. SSMIS onboard the DMSP F18 satellite is the first instrument that has been calibrated to the RSS Version 8 standard.

The data collection deals with the optical data (i.e., video and still imagery) collected by natural light stereo cameras mounted on a MOdular Underwater Sampling System (MOUSS). The data collection consists of natively collected still images (5 frames per second) as well as the full length video and video segments that were created from original still images. Video annotations exist for the video segments; annotations are currently housed within a spreadsheet. The purpose was to execute a testbed study designed to evaluate the performance of transitional advanced technologies.

This data collection consists of archived Geostationary Operational Environmental Satellite-R (GOES-R) Series Geostationary Lightning Mapper (GLM) Level 0 data from the GOES-East and GOES-West satellites in the operational (OPS) and the post-launch test (PLT) phases. The GOES-R Series provides continuity of the GOES mission through 2035 and improvements in geostationary satellite observational data. GOES-16, the first GOES-R satellite, began operating as GOES-East on December 18, 2017. GOES-17 began operating as GOES-West on February 12, 2019.

The GOES-R Advanced Baseline Imager (ABI) Fog/Low Stratus (FLS) products contain estimates of low cloud/fog thickness and probabilities of reduced aviation visibility for Marginal Visual Flight Rules, Instrument Flight Rules, and Low Instrument Flight Rules from the Advanced Baseline Imager (ABI) instrument. Also, the FLS probability products include information when higher clouds mask the satellite view of low clouds, and screens out regions of elevated stratus to highlight areas where the cloud ceiling likely meets the categorical thresholds.

The GOES-R Advanced Baseline Imager (ABI) Cloud Cover Layers (CCL) product contains estimates of cloud fraction between predefined atmospheric levels, as well as, the total cloud fraction at a specified spatial resolution. There are five flight levels of cloud fractions classified as low, middle, and high clouds. The 5 layers defined in feet are: surface to 5000, 5000 to 10000, 10000 to 18000, 18000 to 24000, and 24000 to top of the atmosphere. The horizontal spatial resolution of the products are 10km for full disk and CONUS, and 4km for mesoscale.

The purpose of this collection is to provide researchers and near real-time users, a daily view of river and standing water flooding over the Americas. On the GOES-R series satellites flood detection is based on 10-minute full disk scans first, and then a composition process is done on all the previous 10-minute flood maps to update the results each hour. The product within this collection is a cloud free composite based on 24 hourly map composites. The data are gridded on an equal latitude-longitude area grid.

The NOAA Polar Orbiting Satellite (POES) Global Visible and Infrared Band Data from ESSA (1966 - 1972) and NOAA (1972 - 1978) Satellites data set, provided in NetCDF format, was created by scanning satellite images held in the NCEI Physical Archives. Data were scanned from either 35 mm film or paper photographs, then converted to NetCDF format with navigation information to improve accessibility and use in modern satellite applications. Data are mapped to a polar stereographic grid with a grid cell size of approximately 10 km.

This NOAA Climate Data Record (CDR) contains the AVHRR Polar Pathfinder (APP) product. APP is a fundamental CDR comprised of calibrated and navigated AVHRR channel data (reflectances and brightness temperatures), viewing and illumination geometry (sensor scan angle, solar zenith angle, and sun-sensor relative azimuth angle), Universal Coordinated Time (UTC) of the data acquisition, and a surface type mask. The data are twice daily composites of up to 23 orbits on a 5 km Equal-Area Scalable Earth (EASE)-Grid twice daily over both poles, the Arctic and Antarctic, from 1982 to the present.

NOAA Climate Data Record (CDR) of the eXtended AVHRR Polar Pathfinder (APP-X) cryosphere contains 19 geophysical variables over the Arctic and Antarctic for the period 1982 - present. All of them have undergone various degrees of validation, though not all are considered CDR quality.
