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.

GOES Satellite Data - VISSR/VAS (GOES-7 and earlier) - The Geostationary Operational Environmental Satellite (GOES) series of satellites goal is to monitor the atmosphere for severe weather development such as tornadoes, flash floods, hail storms and hurricanes. The positioning of the GOES satellites at around 36,000 km (22,000 statute miles) above the equator at a fixed position above the earth allowed them to scan large geographic regions of the Western Hemisphere and as frequently as once every half hour.

*This version has been superseded by a newer version. It is highly recommended for users to access the current version. Users should only access this superseded version for special cases, such as reproducing studies. If necessary, this version can be accessed by contacting NCEI.* The NOAA Global Surface Temperature Dataset (NOAAGlobalTemp) is a blended product from two independent analysis products: the Extended Reconstructed Sea Surface Temperature (ERSST) analysis and the land surface temperature (LST) analysis using the Global Historical Climatology Network (GHCN) temperature database.

The product referred to as nClimGrid-Daily is a set of daily gridded fields and area averages of temperature and precipitation that covers the Contiguous United States (CONUS) from 1951 to present and is updated daily. It is related to the monthly version of NClimGrid and NClimDiv, but with a daily temporal resolution. The gridded fields are stored in netCDF format with one file per data month. Area averages for nine types of regions are provided in CSV format with one file per region type and data month.

The U.S. Naval Research Laboratory developed Extreme Ultraviolet (EUV) spectroscopic experiments flown on the NASA Skylab manned space station to study the Sun’s chromosphere, transition region and inner corona. The data include measurements of spectra from specific solar activity regions on photographic film taken by the S082A Spectroheliograph and the S082B Spectrograph instruments that were part of the Apollo Telescope Mount (ATM) Experiments aboard Skylab during three mission periods in 1973 and 1974.
