Abstract
Comparisons of the integrated liquid water content from a ground-based microwave radiometer and PMS observations with the Cloud Optical Thickness (COT) of EOS/MODIS cloud products are carried out, respectively. Two equations are obtained for describing the relationship between cloud liquid water content and COT. Results show that the two slopes of fits are very close, and the former equation is better than the latter.The equation is applied to calculate cloud liquid water content at given time, and the results are compared with Water Path of MODIS. It shows that they have great agreement in layers under stratus cloud.
