WebIn section 2, RRTM and the CCM3 longwave model are described in greater detail, and the modifications made to RRTM to prepare it for implementation into the GCM are discussed. Single-column comparisons of the radiation models are presented in section 3 for two clear-sky profiles and several cloudy-sky cases. http://climatemodels.uchicago.edu/
http://rtweb.aer.com/rrtm_frame.html WebAug 2, 2024 · 1 Introduction. The Earth's climate is shaped by the net top-of-atmosphere (TOA) radiation energy distribution at different latitudes. The solar radiation retained by the Earth exceeds its thermal radiation in the low latitudes, which results in a net radiation surplus; the opposite, i.e., a net radiation deficit, occurs in the high latitudes.
WebIn RRTM_SW, radiative transfer can be calculated with the discrete-ordinates model (DISORT), or with a faster, though less accurate 2-stream method derived from the collaborative 3ARM radiation model. Figure 1 shows fluxes and heating rates calculated by RRTM using DISORT with 16 streams (left panels). WebApr 1, 2012 · RRTM (Mlawer et al., 1997) is a rapid radiation transfer scheme that has been widely adopted in many operational climate- and NWP-systems, such as the WRF model and GRAPES (Chen and Shen, 2006). It utilizes the correlated- k method ( Goody et al., 1989 ) whose k -distribution is constructed with precalculated absorption coefficients from …
