Time-Sampling Errors of Earth Radiation From Satellites: Theory for Outgoing Longwave Radiation
IEEE Transactions on Geoscience and Remote Sensing, 2015The measurements of radiation budget by satellites in low Earth orbit provide limited sampling of the diurnal cycle. Thus, maps of monthly mean radiation fluxes contain errors due to this limitation. The Earth Radiation Budget Experiment reduced these errors in the data products by using a half-sine fit to account for regional diurnal cycles.

The Status of the NOAA Outgoing Longwave Radiation Data Set
Bulletin of the American Meteorological Society, 1984Abstract National Oceanic and Atmospheric Administration (NOAA) satellites have provided over eight years of observations from which estimates of the earth's total longwave emittance can be derived. Changes in satellite instrumentation, orbit, and algorithms used in obtaining these estimates are briefly summarized.

An Earth Outgoing Longwave Radiation Climate Model. Part II: Radiation with Clouds Included
Journal of Climate, 1988The model of the outgoing longwave radiation (OLWR) of Yang et al. (1987) is modified by accounting for the presence of clouds and their influence on OLWR. Cloud top temperature was adjusted so that the calculation agreed with NOAA scanning radiometer measurements.

A Technique for Estimating Outgoing Longwave Radiation from HIRS Radiance Observations
Journal of Atmospheric and Oceanic Technology, 1989Abstract A new technique for estimating outgoing longwave radiation from observations on the NOAA operational satellites has been developed from a regression analysis of radiation model calculations. The technique consists of a weighted sum of radiance in but four intervals sensed by the High-resolution InfraRed Sounder (HIRS).

Annual and Interannual Variations in Outgoing Longwave Radiation over the Tropics
Monthly Weather Review, 1981Abstract Four years of satellite observations of the outgoing longwave radiation have been used to study the distribution of cloudiness and rainfall over the tropics. Annual and interannual variations are described, partially with the help of an eigenvector analysis. Interannual variations in the outgoing longwave radiation are particularly interesting

The Climatology of the Itcz Based on Outgoing Longwave Radiation
1987The outgoing longwave radiation data derived from the NOAA polar orbiting satellites during the period from June 1974 to May 1984 have been used to construct the climatic charts of the ITCZ on the whole globe. The monthly variation of the ITCZ over different parts of the tropical continents and oceans is inspected separately.

Interannual Variability and Climatic Noise in Satellite-Observed Outgoing Longwave Radiation
Monthly Weather Review, 1983Abstract The interannual variability (IAV) in monthly averaged outgoing infrared radiation (IR, from the NOAA polar orbiting satellites) is observed to be larger during summer than during winter over the north Pacific Ocean. A statistical analysis of the daily observations shows the daily variance to be similar during both seasons while the ...

Terrestrial Outgoing Longwave Radiation as measured with CLARA onboard NorSat-
The Earth Radiation Budget at the Top of the Atmosphere (ToA) governs the status of climate change on our planet. The ERB is the balance between the incoming Total Solar Irradiance (TSI) and total outgoing radiation at the ToA. If more energy is stored in the system the Earth Energy Imbalance is positive and the temperature in the system rises.Margit Haberreiter +2 more

El Niño and Outgoing Longwave Radiation: Observations from Nimbus-7 ERB
Monthly Weather Review, 1986Nimbus-7 longwave radiation data are analyzed with respect to temporal and spatial changes in the anomalies induced by the El Nino event of 1982-1983. The components and functions of the earth radiation budget (ERB) instruments, which record satellite-altitude irradiances, are described.

Intraseasonal Circulation and Outgoing Longwave Radiation Modes During Northern Hemisphere Winter
Monthly Weather Review, 1983Abstract An eigenvector analysis is used to characterize global-scale, intraseasonal variability in satellite-derived outgoing longwave radiation fields and NMC analyzed circulation fields. Five-day average covering November-March of 1974–75 through 1979–80 comprise the data sample.
