Cloud Flags of MOD21 (TES) Products
Posted: Sun Jul 16, 2023 10:35 pm America/New_York
I have been trying to use TES-based LST products by using APPEARS software. Even though I followed quality standards defined in the user handbook, there are LST values that are unreasonable above physical limits, like more than 100 °C in Aqua night products. The exact pixel has a much more reasonable value, like 31 °C for the VIIRS product. I noticed Night products of Terra and Aqua (TES MOD21) don't have any cloud-free flags (Only "thin cirrus" and "Pixel within 2 pixels of nearest cloud"). It is unreasonable for me that there is no "cloud-free" pixel for three years.
