Problems getting SST data with tiny lagoons
Posted: Sat Jun 22, 2019 9:56 pm America/New_York
Hello,
Look at this tiny lagoons I attach from the north of Chile (you can see the lat/lon of that rectangle at right). I ordered some L2 SST images from all sensors but I don't know why the southern lagoon (with central point the one that is marked with a circle: -69.14 ° W, -18.24 ° S), which is bigger that the one up of it, has no data in any satellite/sensor... but the one in the north has data.
What property of the water could cause this?
And second... I though to use the information from the north lagoon as "proxy" of the lagoon in the south. But when I apply the standard SeaDAS procedure (my order considered some data from the ocean, in order to have more valid pixels), the data dissapear. Why this happen? SeaDAS doesn't work with lagoons? Or I have to apply another procedure different from the standard one?.
Thank in advance,
Regards,
Marco
