This document is a summary of the major problems in atmospheric radiation, together with recommendations for appropriate action, as evaluated by the U.S. Atmospheric Radiation Working Group (ARWG). It is intended for information and possible use by atmospheric scientists, scientific committees, agencies engaged in the support of atmospheric research, and those who have the responsibility for planning future scientific programs.

The report summarizes the present status and outlines the major unsolved problems of the following five aspects of atmospheric radiation: 1) radiative transfer in realistic atmospheres, 2) radiative energy budgets, 3) radiative properties of atmosphere and surface, 4) radiative instruments and measurements, and 5) radiative interactions in dynamical systems. The final, and probably most important, section consists of recommendations for action that can be taken now to start filling the gaps in our knowledge of atmospheric radiation which are considered by the ARWG to be of highest priority. A list of members of the ARWG steering committee is included in the Appendix.

1 The Atmospheric Radiation Working Group (ARWG) is an informal and independent ad hoc coalition of scientists (mostly U.S.) who are interested in atmospheric radiation, and who convene workshops to exchange information, discuss problems of mutual interest, and foster coordinated research on outstanding problems. Arrangements for meetings and publication of reports such as this are made by the National Center for Atmospheric Research.
