An Assessment of Data from the Advanced Technology Microwave Sounder at the Met Office

Figure 7

NEΔT for ATMS, derived from warm view counts. Light blue: total noise for individual samples, using the method described in Section 3.3; orange: noise estimates from global SDR files; black: for 3 × 3 sample averaging (i.e., field of view for channels 3–15 comparable with AMSU-A). The values for total noise and 3 × 3 noise were derived from one month of direct broadcast data received at Exeter (November 2014).
