Environmental Radiation Data (ERD) is an electronic and print journal compiled and distributed quarterly by the Office of Radiation and Indoor Air's National Air and Radiation Environmental Laboratory (NAREL) in Montgomery, Alabama. It contains data from RadNet (previously known as ERAMS.)

RadNet, formerly Environmental Radiation Ambient Monitoring System (ERAMS), is a national network of monitoring stations that regularly collect air, precipitation, drinking water, and milk samples for analysis of radioactivity. The RadNet network has been used to track environmental releases resulting from nuclear emergencies and to provide baseline data during routine conditions.

RadNet Deployable Monitoring is designed to collect radiological and meteorological information and data asset needed to establish the impact of radiation levels on the environment. The RadNet Deployable System has been designed as a tool for radiological emergency response and can be used to support the current fixed stations of the EPA's RadNet monitoring network. It can also be used as a tool for monitoring areas associated with a real or perceived nuclear or radiological threat.

RadNet-Air is a national network of air monitoring stations that regularly collect air samples for near real time analysis of radioactivity. The data is transmitted to NAREL in Montgomery Alabama. The RadNet-Air network has been used to track environmental releases resulting from nuclear emergencies and to provide baseline data during routine conditions.

RadNet is a national network of monitoring stations that regularly collect air for analysis of radioactivity. The RadNet network, which has stations in each State, has been used to track environmental releases of radioactivity from nuclear weapons tests and nuclear accidents. RadNet also documents the status and trends of environmental radioactivity

ERBE_S7_NAT_1 is the Earth Radiation Budget Experiment (ERBE) S-7 Monthly Medium-Wide Data Tape (MWDT) data set, which is in Native (NAT) format. The MWDT (S-7) product contains a condensed version of the non-scanner data that were found on a monthly set of Processed Archival Tapes (PAT), except that the shortwave estimates of the radiant exitance at the top-of-atmosphere (TOA) were based on the mostly cloudy over ocean bidirectional model. The MWDT product then provided a consistent data set of non-scanner TOA estimates which were not dependent on the operational status of the ERBE scanner instrument.ERBE was a multi-satellite system designed to measure the Earth's radiation budget. ERBE instruments flew on a mid-inclination National Aeronautics and Space Administration (NASA) Earth Radiation Budget Satellite (ERBS) and two sun-synchronous National Oceanic and Atmospheric Administration (NOAA) satellites (NOAA-9 and NOAA-10). Each satellite carried both a scanner and a non-scanner instrument package. The S-8 contained all satellite and viewing geometry, and all scanner and non-scanner radiometric measurements in engineering units with flags defining their validity. It also contained quantities such as scanner measurements corrected to flat spectral responses, the scene identified for each scanner pixel, the estimate of radiant flux at the top-of-the-atmosphere (TOA) for each scanner pixel, and the estimates of the radiant fluxes from the non-scanner measurements. The data were for a 24-hour period and one satellite. If all three satellites were operational on the same day, three separate S-8s were required for a full set of ERBE data. The data period started at Greenwich midnight (zero Universal Time) and continued for 24 hours and the period was divided into 16-second intervals.

ERBE_S9_NAT is the Earth Radiation Budget Experiment (ERBE) S-9 Scanner Radiant Flux data set. It contains inverted daily, monthly hourly, and monthly averages of shortwave (SWF) and longwave (LWF) radiant fluxes at the top-of-atmosphere (TOA) for ERBE scanner data in native format for one month. Data collection for this data set is complete. ERBE was a multi-satellite system designed to measure the Earth's radiation budget. The ERBE instruments flew on a mid-inclination National Aeronautics and Space Administration (NASA) satellite Earth Radiation Budget Satellite (ERBS) and two sun-synchronous National Oceanic and Atmospheric Administration (NOAA) satellites (NOAA-9 and NOAA-10). Each satellite carried both a scanner and a non-scanner instrument package. The scanner instrument package contained three detectors to measure shortwave, longwave, and total waveband radiation. Each detector scanned the Earth perpendicular to the satellite ground-track from horizon-to-horizon. The detectors were thermistors which used space views on every scan as a reference point to guard against drift. The total channel had no filter, so it absorbed all wavelength. The shortwave channel had a fused silica filter which transmitted only shortwave radiation. The longwave channel had a multilayer filter on a diamond substrate to reject shortwave energy and accept longwave. The S-9 contained inverted daily, monthly hourly, and monthly averages of shortwave and longwave radiant fluxes at the top-of-the atmosphere which were averaged into 2.5 degree regions. A S-9 data set was produced for each satellite (ERBS, NOAA-9, and NOOA-10) and the combination of satellites which were operational during the data month. The data set contained a 30 byte header, 67 scale factors - which were used to scale the data in the first record, and 26 scale factors - which were used to scale the data in the second record. The data set also contained two types of records for each processed region. The first record was of fixed length (1860 words) and contained averaged data. The second record was of variable length containing individual hour box estimates. The length of the second record, in words, was calculated by multiplying the number of hour boxes (1846th word of record one) by the number of values passed by hour box which is 32 for the scanner.

This RadNet Quality Data Asset includes all data since initiation and when ERAMS was expanded to become RadNet, name changed to reflect new mission. This includes the milk, soil, air and water components.

ERBE_S4G_SC_NEST10_1 is the Earth Radiation Budget Experiment (ERBE) S-4G Scanner (SC) 5 degree nested to 10 degree Regional Averages data set, which in in Hierarchical Data Format. Data collection for this data set is complete. ERBE was a multi-satellite system designed to measure the Earth's radiation budget. The ERBE instruments flew on a mid-inclination National Aeronautics and Space Administration (NASA) Earth Radiation Budget Satellite (ERBS) and two sun-synchronous National Oceanic and Atmospheric Administration (NOAA) satellites, NOAA-9 and NOAA-10. NOAA-9 and NOAA-10 provided global coverage and the ERBS provided coverage between 67.5 degrees north and south latitude. Each satellite carried both a scanner and a non-scanner instrument package. The scanner instrument package contained three detectors to measure shortwave (0.2 to 5 microns), longwave (5 to 50 microns) and total waveband radiation (.2 to 50 microns). Each detector normally scanned the Earth perpendicular to the satellite ground-track from horizon-to-horizon. The detectors were thermistors which used space views on every scan as a reference point to guard against drift. They were located at the focal point of a f/1.84 Cassegrain telescope, whose aluminum-coated mirrors were overcoated to enhance ultraviolet reflectivity. The total channel had no filter; therefore it absorbed all wavelengths. The shortwave channel was a fused silica filter which transmitted only shortwave radiation. The longwave channel was a multilayer filter on a diamond substrate to reject shortwave energy and accept longwave. To enhance the spectral flatness of the detectors, each thermistor chip was coated with a thin layer of black paint. The effective field of view of the scanner was 3 degrees. The ERBE S-4G product contained averages of radiant flux and albedo on regional, zonal, and global scales. The data for the S-4G product were arranged by parameter values. The various combinations of the satellites reflected the actual duration of the scanners.
