Re: L2gen error with 3x3 straylight masking

Thanks Sean, for next time I'll make sure SeaDAS is updated first....

I wonder if the working / not working has something to do with spatial coverage in the bands used. Regardless, thanks for looking. Cheers

Re: L2gen error with 3x3 straylight masking

Hey Sean, Thanks for looking. Yeah, that file does produce a GEO file with a "1"...lots of those in 2006/2007. I re-checked and this file still fails for me with 3x3 but passes with 7x5 (accting for the "1" in the GEO file :) ). With 3x3: Loading SSES table from /home/hilborna/oc...

Re: SeaWiFS L2 MLAC files missing?

Hi Sean,

Thanks for writing that out. It's useful background (and helpful info if you're like me and don't have much experience using SeaWiFS data).

Cheers!

SeaWiFS L2 MLAC files missing?

Hi ocean colour folks, I'm downloading the available MLAC L2 ocean colour SeaWiFS files for a region in the arctic (western Canada between 67 and 76 degrees N, all L2_MLAC_OC files). After 2004, the number of MLAC files hosted online is greatly reduced and I'm wondering why this is? I cross-referenc...

Bin numbers to lat lon

Hi ocean colour folks, I'm making daily composites of chlor_a at 1km resolution by running l2bin on MODIS-Aqua level-2 files. Then I'm using R to open the binned files and analyze further. 1) I can't convince l3bindump to do my bidding so far - it will produce an empty text file, though mapping the ...

MODISA 250m processing info

Hi ocean colour forum, very quick question - sorry if this is posted somewhere obvious.Can you tell me how the MODISA processing with l2gen implements 250m resolution processing? I'm assuming the 250m bands are used to interpolate the 1km bands, and if I'm correct, how is this done?Thank you...

Wget constantly redirected

As a follow up, that seems to have fixed it, thanks amscott. :)

Eg.
wget --load-cookies ~/.urs_cookies --save-cookies ~/.urs_cookies --auth-no-challenge=on --content-disposition https://oceandata.sci.gsfc.nasa.gov/cgi/getfile/${l2nasa_file}
