Re: MERIS name convention and processing

Also, I wonder if you guys have plans to "repack" the new names to the old name convention after you receive all MERIS L1 files from ESA. Thanks!

Re: MERIS name convention and processing

Thanks John. My search actually returned a mixture of both old filenames (MER....) and new filenames (EN1....). Are the old files still available through the same search? Sean just let me know that SeaDAS8 is able to process the new filenames but SeaDAS8 is just a beta version. If for the same granu...

MERIS name convention and processing

Dear colleague: I used to be able to search the oceancolor.gsfc.nasa.gov site and download and processing MERIS L1 file (using l2gen) in the following name convention: MER_FRS_1PPEPA20040624_091920_000002282028_00036_12114_1284.N1.bz2 But now the same search resulted in the following filename: EN1_M...

HICO radiometric calibration

Thanks again. In addition to calibration, I am puzzled by the SeaDAS Lt output for HICO - they are smeared for most (but not all) pixels. In contrast, rhos output is not smeared. Then I must assume that SeaDAS output Lt is different from the Lt used to calculate rhos. This doesn't make any logic...

HICO radiometric calibration

Thanks Sean. Neither calibration appears correct. Furthermore, the Lt output appears smeared over small bright targets but rhos has the original resolution. Who is in charge of coding l2gen for HICO? Amir? I need to talk to him through email then. Cheers, Chuanmin

HICO radiometric calibration

Dear colleague:I was trying to find how HICO Lt is vicariously calibrated during L1B =>L2. There are two files under the SeaDAS folder ocssw/share/hico/cal:Gao_scaling_factor_Final_1_2012.txtHICO_10727_scaling_factors.txtWhich one is actually used? Is there a paper to document the calibration?Thanks...

MODIS L0 file download

I used to use curl to download L0 files in the name convention AYYYYDDDHHMMSS.L0_LAC.bz2, but it no longer worked. Instead, the original name MOD00.PYYYYDDD.HHMM_1.PDS.bz2 still worked. See below for the downloading results for the same L0 file:-rw-r--r-- 1 hu hu       665 Jul 15...

wget EarthData Login does not work

Sean: thanks so much for diagnosing, and sorry for replying late. I actually have no idea what's going on, but now I wrote a script to check the downloaded files after each round, and the leftovers (compared with the original list) are downloaded the next round - until all files are downloaded. ...

wget EarthData Login does not work

Thanks Sean and team. But replacing cgi with ob didn't work. I still had the same problem. The weird thing is, the "N" appears to be proportional to the total number of files in my download list. For example, if I have 5000 files to download, then after 1200 files (N=1200) it failed. I...
