Dust Constraints from joint Observational-Modelling-experiMental analysis – DustCOMM Version 1
NOTE: PLEASE, USE THE LATEST VERSION 1.1 OF THIS DATASET
This is the version-1 of DustCOMM dataset (Adebiyi et al. Geoscientific Model Development), containing annual and seasonal climatologies of constrained dust aerosol properties, including spatially-varying dust size distribution, mass extinction efficiency, and atmospheric dust loading.
Please be aware that there will be future versions of DustCOMM that incorporates more observational, modeling and experimental constraints.
Please send an email to the corresponding authors if you have any question or would like to receive update of DustCOMM's future developments.
Below, we give a brief description of each data file. In each, we have included the mean, median, 1 and 2 sigma uncertainty estimates as a function of location. These uncertainty estimates are derived from probability distributions that describe the field over each location. Please contact the corresponding authors if you are interested in the full dataset.
The dimensions in these dataset are denoted as:
lon [144] -- Longitude. Unit of degrees_east. Global - 2.5 deg resolution.
lat [96] -- Latitude. Unit of degrees_north. Global - ~2 deg resolution
lev [35] -- Pressure levels. Unit of hPa. ~900 hPa to 100 hPa. Lower resolution in the boundary layer and higher resolution in the free troposphere.
D [200] -- Dust Geometric Diameter. Unit of microns. From 0.2-20 microns.
nseas [4] -- Seasons. They are DJF, MAM, JJA, and SON corresponding to December-January-February, March-April-May, June-July-August, and September-October-December respectively.
