We describe the theoretical advances that influenced the experimental creation of vibrationally and translationally cold polar $^{40}$K$^{87}$Rb molecules \cite{nphys08,science08}. Cold molecules were...
Modelling longwave radiation to snow beneath forest canopies using hemispherical photography or linear regression
forest snow canopy radiation modelling longwave radiation hemispherical photography
font style='font-size:12px;'>
2014/4/3
Forest canopies reduce shortwave radiation and increase longwave radiation reaching the underlying surface, compared with
open areas, and thus influence rates at which forest snowpacks melt. Th...
