Re: SeaDAS MODIS Cloud Mask

When you say "Product", you mean target product on the Math Band popup? Otherwise I do not get an option to select the product after clicking "Edit Expression". The problem I'm running into here is that the MODIS product MOD35_L2 isn't an easy binary mask, the actual cloud mask i...

SeaDAS MODIS Cloud Mask

Is it possible to import the MODIS product MOD35_L2 into SeaDAS to apply a cloud mask to the L1B product MOD02HKM?

So the L1B reader automatically scales it to TOA reflectance for you? Do you have a source so I can cite that?

Re: Project Terra MODIS L1B Swath to L3 500m Sin Grid

Thank you so much! The tool is exactly what I need. I guess the only other question I have is and I can't seem to find it, does it automatically scale to TOA reflectance with the MOD02HKM product? It seems like it does, but I'm not 100% sure, or if I needed to scale it to radiance, I'm not sure wher...

Re: Project Terra MODIS L1B Swath to L3 500m Sin Grid

Oh thank you so much! In the post processing option, I chose sinusoidal with bilinear resampling for the L1B data. The resulting images, however, do not appear to line up with the MODIS sinusoid tiles easily, is there a way to do that? Attached is swath and sinusoid grid I'm looking to overlay, with...

Project Terra MODIS L1B Swath to L3 500m Sin Grid

Hi, I am currently trying to use the two MODIS products L1B MOD02HKM and L3 MCD12Q1 to determine the TOA reflectance of each IGBP land cover type. The problem I am running into is how to project the swath format for L1B to the 500m sin grid of the L3 product. Since the swath projection tool is no lo...
