SMOS The Level 2 Soil Moisture (SM)

[abdullahhuzeyfe]

How can I process soil moisture data using the SNAP program? What can I do? I want to make a soil moisture map of my country. My homework time is short. Can you help me?

If you just need a quick map of soil moisture, these approaches might be sufficient:

• Download and Extract Soil Moisture Data from Sentinel 1 and SMAP using ArcGIS Desktop
• Soil moisture retrieval

Also: Can anyone tell me how retrieve soil moisture using SMOS algorithm in SNAP

Maybe I was too strict in this post:

First you need to install the SMOX-Box. You get it it via the Plugin window in the Tools menu. Then you can read it directly from the SMOS data files (MIR_SMUDP2). If you only have L1 data, like MIR_SCLF1, then you can’t compute it. The SMOS-BOX is intended for inspecting SMOS data, not for processing. I don’t think that Band Math can be used with a simple equation.

A binning or a mosaic is probably possible, afterwards a shapefile of your country can be used to mask the data. But this is only technically spoken. No guarantee that ii is scientifically correct.

well, the tutorials above are two examples to get the soil moisture content at national scale.
