Actually this is the correct way to open the files.
Which file do you select when you try to open SMOS.
May be it is somehow corrupted.

You are also still using an older (4.9) version of BEAM.
Try updating to 4.10 (not 4.11, for this we don't have an updated SMOS-Box yet.).
In this version you should simply use the 'File --> Open Product' menu entry.
You can select the .HDR or the .DBL.

Thank you very much for your reply, I according to what you have said to try, it's very successful.
But I still have some questions. Beam is issued according to the data accumulation and update on time? Is a sensor that is the data format will change every year?Why must be so frequent change version for users in trouble?
Hope you reply as soon as possible.

Hi,

I'm glad to hear that.

Beam is issued according to the data accumulation and update on time?


New versions of BEAM are released when specific milestones are reached, there is no fixed release plan at the moment.

Is a sensor that is the data format will change every year?Why must be so frequent change version for users in trouble?


I'm not sure if I understand you correctly, but we are not responsible for changing data formats; you should ask the data vendors this kind of question.

Best regards,
Thomas

I imported smosL1c and L2 data, window displays a picture. I chose one of the data, click on "SMOS snapshot information tool", but it always show "NO SMOS image selected. Why?

SMOS L2 products do not exhibit snapshots. The Snapshot Information Tool can only be used with SMOS L1C data products. In order to employ the Snapshot Information Tool, an image from a L1C product has to be opened first.

This makes sense, because the Snapshot Information Tool is a tool for selecting the data (i.e. the snapshot within the product) that serve as as source for the displayed images.

You can create a subset of the product by scrolling and zooming to the area of interest and do a right-click.
From the context menu you can select 'Spatial Subset from View...'. or you chose from the menu File -> New product....

Yes this is a fixed choice.
You can either add new coordinates, load them from a previously saved pin file or import from a csv file.

Please have also a look at this help page

Dear Cui Hui Zhen,

I do not fully understand your question. I assume that you have opened a SMOS L2SM product in VISAT, correct? Now: where and how do you output the data? To which format, with which tool?

Whether the output data can be used directly or not, this largely relies on your requirements on the data.

Can you please provide a bit more information.

Thank you,

Tom

I mean i used the "Pin Manager" -" import Pins (with insitu site's Lat/Lon)-sellect all "Available Bands And Tie Point Grids"-'Export Pin data Table", this export file format is "txt", This txt file include some parameters :"Soil_Moisture"、“Soil_Moisture_DQX” 、“Optical_Thickness_Nad”and so on。 Is these export parameters need further processing? Can the parameter "Soil_Moisture" value Compared with the insitu soil moisture directly?
Thanks!

The product specification says that Soil_Moisture contains:
An estimate of surface soil moisture obtained through a successful retrieval of this parameter

The unit is m³/m³
So I would think you can compare it with your insitu data if it has the same unit. But in general it is up to you to decide if you can compare the data.


cheers
