Re: l2bin/l3bin/l3mapgen distortion for non-standard data product

It was in fact the latter. It was a 32bit array I labeled as 64.
Thank you for all the help!

Re: l2bin/l3bin/l3mapgen distortion for non-standard data product

As far as I can tell it was mis-handled in the binning workflow. When I added my new variable to the l2gen produced netcdf file I designated the new variable as a float64 (which I changed to 32-bit the other day) and I guess during binning it was processed as a 32-bit data. I am not entirely sure ho...

Re: l2bin/l3bin/l3mapgen distortion for non-standard data product

Hi, I just wanted to update on this if anyone in the future comes across a similar issue. As gnwiii commented, if l2bin/l3bin/l3mapgen are working, the problem isn't with the xml file where I added the new product/algorithm. Following gnwiii's suggestion, I used gdalinfo to inspect the netcdf l2 fil...

Re: l2bin/l3bin/l3mapgen distortion for non-standard data product

Thank you for the reply. I am pretty sure I had a used the get_product_info command after editing the product.xml file to see if it was added, but I should double check to see how it fully compares with the standard chla product.

l2bin/l3bin/l3mapgen distortion for non-standard data product

Hi all, I am trying to test an MDN approach to retrieve chl a using MODIS Rrs (see Pahlevan et al. 2020, https://www.sciencedirect.com/science/article/pii/S0034425719306248). I am using L2 data files I created using the standard l2gen (at 1000m resolution). Afterwards, I use the Rrs in the model and...

L2gen processing speed

Hi all,I am currently working on a long term time series with MODIS nFLH and ocean color. I am using this parameter to calculate the quantum yield of fluorescence. For this I need the senz data product.Since this is not a standard product I am processing from L1. I am happy to download all the stand...

Failed download for some AQUA L2 OC files

Hi,
Is this still an issue?
I see the reply is from June 2nd 2020. I am currently having a similar issue with dowloading my l1 MODIS data order.
Thank you,

zenith angle of observation

Thank you for the response.A far as I can tell from previously doing this I have looked at the long names, so I "know" what csol_z is (not the other two), but I guess for my question, I am not sure if that is in fact the value I need.I am relying on the following quote from Huot et al 2009...
