Error: Operator Exeption - Message Missing band at 560.0 nm

The operator is described in the help (Help / Help Contents)

For specific the meaning of the LAI values, please see: Wikipedia

You can find also the ATBD here:

Hi, i’m getting problems to download the updates

its apearing:

The server may be unavailable at the moment. Try again later.


Not all of the plugins have been successfully downloaded. The server may be unavailable at the moment. Try again later.

I have tryed turn off my antvirus but still the same

So maybe the server takes a nap again.
Also, other users experienced problems.

@oana_hogoiu, can you have look?


and about the sent2cor I can not use… its appearing in the external tools :
Tool executable not found

but I did the “L2A_Process.bat --help” process and it seems to be ok

If this doesn’t help please ask your question regarding sen2cor in the sen2cor category.
There are the experts.

But “Tool executable not found” sounds like you need to configure the path to sen2cor in “Tools / manage External Tools

Ok, thanks, I’ll try

But, if I run the correction in qgis, I can load that output images in sentinel ?

If it is the normal sen2cor output, then yes.

but, to open the images in snap, i have to open by the MTD , no? After I run the correction, how it will opened in snap?

Hello, sir. I can use your method on L1C but not on L2A after atmospheric correction. Will appear Missing band at 560.0 nm. (S2A_MSIL2A_20180820T051651_N0206_R062_T44TPM_20180820T082325.SAFE)

I hope you can help me, or if using L1C has any effect on the results.Please

This happens when you select any other output format than BEAM DIMAP, the metadata gets lost. If you open the image, there should be the bandwidths and wavelengths in each raster’s properties.

Hello, my output format is BEAM DIMAP ,But there was still this problem on the L2A in 2018. When I opened the resampled file, I found that the band B2-B4 was missing.

Hello, my output format is BEAM DIMAP ,But there was still this problem on the L2A in 2018. When I opened the resampled file, I found that the band B2-B4 was missing.
I tried L1C, resampling, and there was no lack of bandwidth.
So I tried to do atmospheric correction again, and the result seemed to be OK.
This problem occurred once in May, August and October in the 2018 images, and was normal in other months. Can you explain it?

if you perform atmospheric correction, make sure you include all resolutions as described here:

That means, you have to perform it for 10, 20 and 60, so that all bands are written in the target product.

Thank you. I corrected it at all resolutions(10m,20m,60m). I feel that there may be some bugs in atmospheric correction.

Hi everyone,
Thanks for helping me, I managed to run the LAI in the end…
but, anyone knows any article about LAI performed by SNAP?

Here is an example of articles concerning LAI

Validation of Sentinel-2 LAI and FAPAR products derived from SNAP toolbox over the Barrax cropland site (Spain)


l have same problem. as l see this data get from Copernicus Open Access Hub.
How is about data download from Land Viewer EOS. that does not give MTD data.
It is provide S2A_tile_20160613_39TTE_0_Product_metadata.xml and this does not opened by SNAP.
what can do in this case?

SNAP needs the S2 data in its original form, e.g. downloaded from the Copernicus Hub, PEPS or other sources which provide the initial product.
The EOS Land Viewer does not offer that (according to my knowledge and the documentation).

thanks for reply.

But MTD data is not opened by SNAP. what may be reason for this result?
