The invention relates to a long-wave downlink
radiation estimation method under cloudy days, a computer storage medium and
electronic equipment, and the method comprises the steps: setting the weatherconditions of cloudy days, obtaining a
simulation library through
simulation according to the weather conditions, and building an
estimation parameterization model based on the
simulation library; acquiring the
cloud top temperature, the
cloud top height, the atmospheric total
moisture content, the surface temperature and the surface
emissivity by
remote sensing; according to the
cloud top temperature, the cloud top height, the atmospheric total
water vapor content, the surface temperature and the surface
emissivity which are obtained through
remote sensing, estimating long-wave downlink
radiation under cloudy days through an
estimation parameterization model. According to the invention, an estimation parameterization model is established according to weather conditions; long-wave downlink
radiation under cloudy days is estimated according to the model and the acquired cloud top temperature, cloud top height, atmospheric total
moisture content, surface temperature and surface
emissivity, calculation of long-wave downlink radiation under cloudy days is realized, and the defect that long-wave radiation under cloudy days cannot be effectively inverted in the prior art is overcome.
