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

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

Hi, i’m getting problems to download the updates

its apearing:

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

I have tryed turn off my antvirus but still the same

marpet · January 31, 2019, 11:49am

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

@oana_hogoiu, can you have look?

bflessi · January 31, 2019, 1:14pm

ok,

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

Please have a look at the following posts:

and

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”

bflessi · January 31, 2019, 2:43pm

Ok, thanks, I’ll try

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

marpet · January 31, 2019, 2:54pm

If it is the normal sen2cor output, then yes.

bflessi · January 31, 2019, 2:57pm

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?

Gufeng · February 23, 2019, 3:12pm

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

ABraun · February 23, 2019, 6:22pm

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.

Gufeng · February 25, 2019, 4:10am

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.

Gufeng · February 25, 2019, 4:29am

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?

ABraun · February 25, 2019, 5:54am

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.

Gufeng · February 25, 2019, 6:04am

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

bflessi · May 2, 2019, 1:03pm

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?

falahfakhri · May 2, 2019, 3:08pm

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)

Hi

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?

ABraun · June 11, 2020, 1:34pm

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).

bext_la · June 11, 2020, 1:49pm

thanks for reply.

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