NSSTNJ
A composite image is created by composing the only nighttime images by a period of 1st 10days/2nd 10 days/3rd 10days of the month from the sea surface temperature data(MCSST) for each path which is calculated from AVHHR reception data of NOAA. In this system, the influence of cloud area is eliminated by adopting the "MAX" values of MCSST in each pixcel, in order to reduce the cloud area in the period (10 days) when the composite image is created. The temperature range of browse images has been created with 256 colors from -2 degrees C to 30 degrees C.

Composing by 1st 10 days / 2nd 10 days / 3rd 10 days, and recognizing it as a daytime data in case the sun elevation angle at the time of reception is 10 degrees or less, the daytime images have been composed.
