Grace (then a tropical storm) is shown in AWIPS above, in between Jamaica and the Caymans, in Day Night Band Visible imagery, along with VIIRS I05 Infrared imagery, from 0626 UTC, using data from the Direct Broadcast site at CIMSS. The coldest cloud tops with the most vigorous convection, shown... Read More

Detection of smoke is a challenge in regions with clouds. The bright reflectance from clouds can make the subtler (and usually not so bright) smoke features difficult to view. This blog post briefly shows how visible imagery can be manipulated to facilitate smoke detection. The animation above shows visible imagery... Read More
