地表上行长波辐射

地表上行长波辐射ULR(surface upwelling longwave radiation)是指地表在其温度下向上发射的长波辐射与反射的大气向下长波辐射通量密度之和，由红外通道辐射率经由一个非线性反演模式计算得到。卫星的地表上行长波辐射产品，时间频率10分钟，空间分辨率2km。

Surface Upwelling Longwave Radiation (ULR) refers to the sum of upward longwave radiation emitted by the Earth's surface at its own temperature and the downward longwave radiation flux density reflected by the atmosphere. It is calculated via a nonlinear inversion model using the radiance from infrared channels. The satellite-derived surface upwelling longwave radiation product has a temporal resolution of 10 minutes and a spatial resolution of 2 km.
