| Subject: | NSA/TSI/C1 - Reprocess: Sky filter thresholds |
| DataStreams: | nsatsicldmaskC1.a1, nsatsiskycoverC1.b1
|
| Description: | The sky filter thresholds are incorrect causing poor fractional cloud cover values.
The cldmask images and fractional sky cover values will be reprocessed by changing the sky
filter thresholds thin_thresh from 45 to 50 and opaque_thresh from 70 to 90. |
| Suggestions: | Do not use data. Wait for reprocessed data. |
| Measurements: | nsatsiskycoverC1.b1: - Pixel count: number opaque in zenith circle(region_zenith_count_opaque)
- Percent opaque cloud(percent.opaque)
- Pixel count: number thin in horizon area(region_horizon_count_thin)
- Pixel count: number thin in zenith circle(region_zenith_count_thin)
