Zero-rain rate IR temperature threshold (Kelvin) in each lat-lon box,
using past 24 hours of co-located geostationary and global SSM/I data
- Zero rain rate threshold automatically determined when the zero rain rate
points are processed in histogram matching process
- Lowest temperature bin is 183 K (purple color, indicates no rain)
- If not sufficient points, lat-lon box is marked “bad” (black color)
