I am new to VIIRS data process so please ignore the mistakes.:sad:
I was trying to process VIIRS data from L1A to L1B using : calibrate_viirs par=VIIRS_2017071.par
used the following par file
ifile=/OceanColour/seadas_7.4_Final_Run/VIIRS_Data/071/V2017071053000.L1A_SNPP.nc
l1bfile_mod=/OceanColour/seadas_7.4_Final_Run/VIIRS_Data/071/V2017071053000.L1B_SNPP.nc
dnb_dynamic_lut_file=VIIRS_NPP_CAL_DNB_DYNAMIC_LUT_v2.0.0.2_obpg.nc
rsb_dynamic_lut_file=VIIRS_NPP_CAL_RSB_DYNAMIC_LUT_v2.0.0.2_obpg.nc
static_lut_file=/home/o-mc/SeaDAS-7.4/ocssw/run/var/viirsn/cal/OPER/VIIRS_NPP_CAL_STATIC_LUT_v2.0.0.2_obpg.nc
straylight_lut_file=/home/o-mc/SeaDAS-7.4/ocssw/run/var/viirsn/cal/OPER/VIIRS_NPP_CAL_STRAYLIGHT_DYNAMIC_LUT_v2.0.0.2_obpg.nc
cmn_lut_file=/home/o-mc/SeaDAS-7.4/ocssw/run/var/viirsn/cal/OPER/VIIRS_NPP_CMN_LUT_v2.0.0.2_obpg.nc
geo_lut_file=/home/o-mc/SeaDAS-7.4/ocssw/run/var/viirsn/cal/OPER/VIIRS_NPP_GEO_LUT_v2.0.0.2_obpg.nc
and got following error:
VcstCalNetcdfInputItem::readNetcdfDynamic() Failure opening LUT file: VIIRS_NPP_CAL_RSB_DYNAMIC_LUT_v2.0.0.2_obpg.nc
VcstCalNetcdfInputItem::getData(iet) Failure reading netCDF dynamic file for LUT F_PREDICTED_LUT
ViirsGranule::read_lut() Error reading LUT data for group name F_PREDICTED_LUT
ViirsGranule::initialize_LUT_data() Failure reading LUTs.
ViirsGranule::LUT initialization failure
VcstViirsCal::Granule initialization failure
Main:: Calibration initialization failure
Am I doing it wrong?:confused:
Can anybody guide me about the steps or can share any useful study links?
And one more question, is the installation of dem file is necessary if I use V*.GEO-M_SNPP.nc geo file?
Thanks in advance.
VIIRS L1A to L1B
VIIRS L1A to L1B
Try using the full paths for the lines:
I don't think the big dem files are needed if you use
dnb_dynamic_lut_file=<** missing path **>/VIIRS_NPP_CAL_DNB_DYNAMIC_LUT_v2.0.0.2_obpg.nc
rsb_dynamic_lut_file=<** missing path **>/VIIRS_NPP_CAL_RSB_DYNAMIC_LUT_v2.0.0.2_obpg.nc
I don't think the big dem files are needed if you use
V*.GEO-M_SNPP.nc
files, and I'm not sure the new version of the processing software even supports the existing dem files.VIIRS L1A to L1B
Ooops.... My bad.
But after adding complete path, it didn't work. Finally a OCSSW update solved the problem.
Any way thanks for pointing out the mistake.
