The STAR GOES Imagery Site team has developed the Day Night Cloud Micro Combo product to more efficiently deliver the observational value of both the Day Cloud Phase Distinction & Night Microphysics RGB products.

Daytime: Day Cloud Phase RGB The daytime period of this RGB helps evaluate the phase of cooling cloud tops to monitor convective initiation, storm growth, and decay. It can also be used to identify snow on the ground. The Day Cloud Phase Distinction RGB takes advantage of cloud reflectance differences between the visible and near infrared channels and temperature variances between land and clouds in the infrared to provide increased contrast between background surfaces and phases of clouds (i.e., water vs. ice). Due to its reliance on visible bands 2 and 5, it is only usable during daylight hours. This composite was developed by the Japan Meteorological Agency (JMA) for Himawari-8. Interpretation is still under investigation.

Nighttime: Nighttime Microphysics RGB The distinction between low clouds and fog in satellite imagery is challenging. While the difference between the 10.4 and 3.9 μm channels has been a regularly applied product to meet aviation forecast needs, the Nighttime Microphysics (NtMicro) RGB adds another channel difference (12.4- 10.4 μm) as a proxy to cloud thickness and repeats the use of the 10.4 μm thermal channel to enhance areas of warm (i.e., low) clouds where fog is more likely. The NtMicro RGB is also an efficient tool to quickly identify other cloud types in the mid and upper atmosphere.
