Results of research on the voles, presented at the annual meeting of the Society for the Study of Evolution in Montreal last month, raises questions about
the full effect of radiation on animal populations and on humans.
We use the 9 climate variables
of surface air temperature (SAT), sea level pressure (SLP), precipitation (rain), the top
of atmosphere (TOA) shortwave (SW) and longwave (LW)
full - sky
radiation, clear - sky
radiation (CLR, radiative flux where clouds do not exists), and cloud radiative forcing (CRF, radiative
effect by clouds diagnosed from the difference between
full - sky and clear - sky
radiation, Cess et al. 1990).
