You can use the Collocate tool with HICO as the reference/master and VIIRS as the dependent file.  This will generate a new file containing all the raster data bands from both input files.  The pixels of the generated file will geographically match those of the L2 HICO pixel.  Since a...

No, you cannot reproject L1 images and then run l2gen.  All the science processors within the OCSSW menu are strict science data processors with specific input file types and formats, tracking through specific science data levels.  The other more generic GUI/GPT tools such as Reproject, Su...

You can apply the flag masks using the original unprojected flag by setting the following field within the Reproject operator:<maskExpression>${maskExpression}</maskExpression>The flags themselves should not be reprojected as they really have no meaning since they are tied to multiple unprojected pi...

I've never used Arcgis, but the shapefile export tool should work fine in SeaDAS for contours.  You can test this by creating contours in SeaDAS, exporting the contours from within the File Info window (right click on Vector and select "Export Geometry as Shapefile").  Then o...

Hi Amita,I'm answering in regards to how you would do cloud masking on a rhos_865 band with other SeaDAS GUI tools instead of cloud masking with l2gen. In the Mask Manager tool window click on "f(x)" icon.  Click "Show bands".  At this point you can click and create...

If you are a loading a level-2 file into SeaDAS the Mask Manager panel shouldn't be blank.  Make sure your file is being loaded correctly and being recognized as a level-2 file.  To determine which "Product reader" SeaDAS is actually using on your file, go to File Manager, cl...

The MODIS instruments only contain 2 bands at 250m (645nm and 859nm).  These are not blue/green or IR bands so it rules out the SST and chlor_a algorithms.  You do have options regarding fine tuning atmospheric correction.  You can use l2gen to process the 645 and 859 band products to...

Yes you can improve the resolution of the level2 flag mask "CLDICE", depending of course on which sensor mission you are using.  I'm guessing that you are referring to MODIS which contains 250m, 500m, 1000m bands and can be processed by SeaDAS at any of these resolutions.  Th...

Very likely, yes you can find data there in June at higher resolutions.  I just used the L2 browser https://oceancolor.gsfc.nasa.gov/cgi/browse.pl and did a quick visual scan of the true color (TC) images and found many files for June 2020 matching your region (most of them cloudy but not all)....

Barry, this case study video tutorial illustrates the use of the Collocation Tool in comparing files and using statistics.
