High-Resolution, Near Real-Time Simulation of Microwave Radiance Using a Simple Land-Cover Based Emissivity Prior

Table 4

Correlation coefficients (COR-Pearson’s method) and RMSE for all channels, between AMSR-E 𝑇_𝑏 values and the SDSU simulated ones, using the proposed emissivity values table (New), the ones after using TELSEM data (TEL), and the original version with a fixed value (Old) for all 3 cases, for nonrainy/cloudy pixels.
