The High-Resolution Infrared Radiation Sounder (HIRS) of intersatellite calibrated channel 12 brightness temperature product is a gridded global monthly time series product spanning from 1979 to the most current full month, updated monthly. Among the twenty channels in the HIRS instrument, channel 12 measures upper tropospheric water vapor. Multiple polar orbiting satellites in the NOAA Polar-orbiting Operational Environmental Satellite (POES) and MetOp series have carried HIRS instruments.

This dataset consists of images and keyed data of daily precipitation strip charts for the country of El Salvador and have a period of record ranging from 1984 to 2010. The strip charts were rescued and imaged by the International Environmental Data Rescue Organization (IEDRO). These precipitation chart forms contain continuous ink traces representing the instantaneous measurement of rainfall amounts for a 24-hour period. The chart form background has a calibrated grid (usually in mm or inches) superimposed on the chart.

This dataset consists of images of records containing meteorological surface observations in both synoptic and monthly formats for over 20 stations in the country of Bolivia. It has a period of record ranging from 1945 to 2010. The observations include (but are not limited to) 6-hourly and daily values of temperature, humidity, cloud coverage, cloud heights, rainfall, and wind speed/direction.

This dataset consists of images of records containing meteorological surface observations in synoptic format for various stations in the country of Paraguay. It has a period of record ranging from 1940 to 1998. The observations include (but are not limited to) 6-hourly values of temperature, humidity, cloud coverage, cloud heights, rainfall, and wind speed/direction.

This dataset contains Commercial (Comm) Radio Occultation (RO) raw data from GeoOptics, which is an established method for remote sounding of the atmosphere. The technique uses an instrument in low-Earth orbit (LEO) to track radio signals from Global Navigation Satellite System (GNSS) transmitters as they rise or set through the atmosphere. The occulting atmosphere refracts or bends the radio signals, and given the precise positions of both satellites, the bending angle can be deduced from the time delay of the signal.

This dataset contains Commercial (Comm) Radio Occultation (RO) raw data from Spire Global Subsidiary, which is an established method for remote sounding of the atmosphere. The technique uses an instrument in low-Earth orbit (LEO) to track radio signals from Global Navigation Satellite System (GNSS) transmitters as they rise or set through the atmosphere. The occulting atmosphere refracts or bends the radio signals, and given the precise positions of both satellites, the bending angle can be deduced from the time delay of the signal.

This dataset contains Commercial (Comm) Radio Occultation (RO) environmental data from UCAR using GeoOptics data, which is an established method for remote sounding of the atmosphere.

The U.S. Annual/Seasonal Climate Normals for 1991 to 2020 are 30-year averages of meteorological parameters that provide users the information needed to understand typical climate conditions for thousands of locations across the United States, as well as U.S. Territories and Commonwealths, and the Compact of Free Association nations. The stations used include those from the NWS Cooperative Observer Program (COOP) Network as well as some additional stations that have a Weather Bureau Army-Navy (WBAN) station identification number, including stations from the U.S.
