Assessments of F16 Special Sensor Microwave Imager and Sounder Antenna Temperatures at Lower Atmospheric Sounding Channels

Table 2

Warm load count anomaly zone identified from SSMIS data March 20, 2005. β _L ~ β _R denotes the latitudes of each anomaly zone width in the left and right sides, respectively. (Δ𝐶_𝑊)_max is the maximum warm load count anomaly for each zone and is estimatedaccording to Figure 3(a). (Δ𝑇^CAL_𝐴)_max is the error in SSMIS radiance corresponding to (Δ𝐶_𝑊)_max, which is determined using the first term in (6), (i.e., −(𝑇_𝐴−𝑇_𝐶)/(𝐶_𝑊−𝐶_𝐶)Δ𝐶_𝑊).
