Re: Terra MODIS Processing on Hold as of December 1, 2022

Does this hold mean the current NRT version of L1A and geofiles on LANCE also not reliable for geolocation?

Find swaths in L1/L2 browser

My plan is to find all L1A of MODIS Aqua that contain any part of my area of interest, i.e. a L1A could be counted even its one frame is in my area of interest. In L1/L2 browser, I suppose the "select swath containing (at least)... " option could help me accomplish this goal. However, I'm ...

Re: Incomplete MODIS L1A granule list on LAADS archive

I appreciate this update. Thank you!

My best regards.

Re: MODIS Terra geolocation files

Hi Sean,

Thank you for sharing this delightful news that OB will distribute Terra GEO.

I was wondering will these Terra GEO include both day and night granules (all day long), i.e. something like you're working on for Aqua GEO update in the R2022 reprocessing?

Cheers,
Hanzhi

Re: Incomplete MODIS L1A granule list on LAADS archive

Thank you!

Is this processing way only applied to MODIS L1A products?

Because at least for MOD06, I can use wget to download the whole day granules without ordering them.

Best,
Hanzhi
