Re: Removing high chlor_a before binning

Hey Sean,

Thanks for your answer! I'll adjust the CHLWARN flag for future. I agree this would be a super useful feature esp at the L2/L3 binning stage for a variety of products.

Cheers, happy halloween 8-) ,

Re: Removing high chlor_a before binning

Hey gnwiii, As I understand you're saying that a threshold is maybe a bit too simplistic a way to remove values. In this case I'm using regular flagging but even so in my region of interest (BC coast), at 1 km resolution many pixels on the continental shelf in the chlor_a product are very high (> 60...

Removing high chlor_a before binning

Hey forum, Apologies if there is an obvious answer. Is there a simple way to remove high chlorophyll-a values before they are included in binned images and composites? I am making daily, 8day and monthly chlor_a composites at 1km resolution using L2Bin > L3Bin > L3Map on downloaded and reprocessed L...

Re: MODIS Aqua reprocessing status 2022

I'll just tack onto this question to ask if the CMR Search website has an estimated date it will sync with the oceancolour site? For MODIS-Aqua both R2018 and R2022 Level-2 files are there, but a number of files from the R2022 processing are still missing. Attached is an image of the 2003 R2018 L2 f...

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...
