USCRN Processed data are interpreted values and derived geophysical parameters processed from raw data by the USCRN Team. Data were interpreted and ingested into a database, but are also available as netCDF files exported from the database. The "Version 2" of the dataset denotes the application of a new precipitation algorithm to calculate values. (See documentation for more information).

Sudden Stratospheric Warming Compendium (SSWC) data set documents the stratospheric, tropospheric, and surface climate impacts of sudden stratospheric warmings. This examines major mid-winter warmings, as defined by a reversal between November-March of the zonal winds at 10 hPa and 60N from westerly to easterly. The one major warming that occurred in the Southern Hemisphere is also included. Analyses are available from 6 different reanalyses: MERRA2 (1980-2014), JRA-55 (1958-2014), ERA-interim (1979-2014), ERA-40 (1958-2002), NOAA20CR (1958-2011), and NCEP-NCAR I (1958-2014).

This dataset includes monthly gridded temperature anomalies on a global 2.5 x 2.5 degree grid derived from Microwave Sounding Unit (MSU) and Advanced Microwave Sounding Unit (AMSU) radiance data since December 1978. In addition, there are monthly regional anomalies and monthly mean annual cycle temperatures. All products are derived for four bulk layers of the atmosphere: the Lower Troposphere (TLT), Mid-Troposphere (TMT), Tropopause (TTP) and Lower Stratosphere (TLS). Version 6.0 is the latest UAH version archived at NOAA and is updated monthly.

The Ground-Based Global Positioning System (GPS) Meteorology Integrated Precipitable Water Vapor (IPW) data set measures atmospheric water vapor using ground-based GPS receivers. The data contain observations from several hundred locations around the globe every 30 minutes from 2002-05-01 to 2016-11-28. However, most locations lie within the continental United States. The data set was formed in response to the need for improved moisture observations to support weather forecasting, climate monitoring, and research.

These data were used to conduct the study of the global surface warming hiatus, an apparent decrease in the upward trend of global surface temperatures since 1998. The data are from 1880-2014 for global land, ocean, and land-ocean areas. The data include both gridded, time series, uncorrected and corrected data. An additional analysis specific to the Arctic is included. There is an Old Analysis and New Analysis; the old being the current operational version running at NCEI at the time.

This dataset, the International Comprehensive Ocean-Atmosphere Data Set (ICOADS), is the most widely-used freely available collection of surface marine observations, with over 455 million individual marine reports spanning 1662-2014-each containing the observations and metadata reported from a given ship, buoy, coastal platform, or oceanographic instrument, providing data for the construction of gridded analyses of sea surface temperature, estimates of air-sea interaction and other meteorological variables.

The Sea Surface Temperature - Woods Hole Oceanographic Institution (WHOI) Climate Data Record (CDR) is one of three CDRs which combine to form the NOAA Ocean Surface Bundle (OSB) CDR. The resultant sea surface temperature (SST) data are produced through modeling the diurnal variability in combination with Advanced Very High Resolution Radiometer (AVHRR) SST observations. The final record is output to a 3-hourly 0.25-degree resolution grid over the global ice-free oceans from January 1988 to August 2021.

The Ocean Heat fluxes Climate Data Record (CDR) is one of three CDRs that make up the NOAA Ocean Surface Bundle (OSB). They can be used to describe essential aspects of the air-sea exchange. This CDR leverages the parameters of surface atmospheric properties and sea surface temperature to calculate the latent and sensible heat fluxes from a neural-network emulator of the TOGA-COARE Bulk Air-Sea Flux Algorithm. The final record is a 3-hourly 0.25-degree resolution grid over the global ice-free oceans from January 1988 to August 2021.

The NOAA Ocean Surface Bundle (OSB) Climate Data Record (CDR) consist of three parts: sea surface temperature; near-surface wind speed, air temperature, and specific humidity; sensible and latent heat fluxes. This portion of the OSB CDR is the NOAA Climate Data Record (CDR) of Ocean Near Surface Atmospheric Properties. Evaluation the near-surface atmospheric temperature, humidity, and wind in comparison to similar values at the sea surface describe essential aspects of the air-sea exchange.

Integrated Global Radiosonde Archive (IGRA) Version 2 consists of quality-controlled radiosonde observations of temperature, humidity, and wind at stations across all continents. Data are drawn from more than 30 different sources. The earliest year of data is 1905, and the data are updated on a daily basis. Record length, vertical extent and resolution, and availability of variables varies among stations and over time.
