Re: How to select low level warm water cloud fraction in MODIS MCD06COSP dataset

Thanks for your kind suggestion! one more thing I want to ask, while computing cloud fraction in MODIS COSP dataset, do the computation consider the effect of overlap cloud layer? Some studies (e.g., DOI: 10.1126/sciadv.adh771) while using MODIS cloud fraction prefer random overlap assumption as: CF...

Re: How to select low level warm water cloud fraction in MODIS MCD06COSP dataset

Okay, I will consider overlapping pixels of “Cloud Mask Fraction Low” AND “Cloud Retrieval Fraction Liquid” for low-level warm cloud selection. Thanks for your kind suggestion. I am using python (xarray and numpy) mask = 1 * numpy.ones((180,360)) * numpy.isfinite(Cloud_Mask_Fraction_Low) low_warm_cl...

How to select low level warm water cloud fraction in MODIS MCD06COSP dataset

Hi all, I am wondering to filter low-level (cloud top pressure >= 680 hPa) and warm (cloud top temperature > 273.0 K) cloud fraction in MCD06COSP level-3 daily cloud properties (https://ladsweb.modaps.eosdis.nasa.gov/missions-and-measurements/products/MCD06COSP_D3_MODIS). I can see two different fla...

Re: Fine mode fraction aerosol over ocean in MODIS SDS

But i am again confused with the specification. Do you consider these two SDS for fine mode information?

Fine mode fraction aerosol over ocean in MODIS SDS

Hello,
I am searching for the SDS related to fine mode fraction (FMF) aerosol over ocean in the latest available MODIS collection 6.1 datasets.
Please help me to find the correct SDS. Thanks!

MODIS Level-2 data post-processing and order

Hi, I am trying to regrid the MODIS_L2 10km Aerosol data from Swath to regular grid. As suggested on hdfeos forum (http://hdfeos.org/zoo/LAADS_MOD_py.php), I am using pyresample (a geo-resample package in python) to do the same. Since the daily MODIS_L2 swath data comes in huge numbers (particularly...

Re: MODIS Level-3 Gridded product: Angstrom Exponent (AE) over OCEAN

Hi, I have gone through the referred doc on https://atmosphere-imager.gsfc.nasa.gov/products/daily/documentation Nowhere the term explicitly defined for the Angstrom Exponent over Ocean . They are providing joint histo of AE vs optical depth. Even I couldn't understand the application of joint histo...
