This dataset presents the time series of modeled aerosol optical properties (light absorption and extinction) from ten earth system models.

The dataset covers the year 2010 and contains the above mentioned optical properties at wavelengths λ = 440, 550, and 870 nm and for different values of the relative humidity (RH = 0, and between 40 – 85 %). The variables are given for a variety of grid points representing latitude and longitude points covering the whole globe (for eight of the models) or given locations (the remaining two models).

The dataset can be used to evaluate models against in-situ measurements of aerosol optical properties.

Data description

The dataset is composed of 2424 netCDF (.nc) files containing multi-wavelength (λ = 440, 550, and 870 nm) particle light absorption and extinction coefficients for the year 2010. For λ = 550 there are, in addition, files for different values of relative humidity, for dry (RH = 0 %) and wet conditions (RH ranging from 40 to 85 %). Total size of dataset: 28 GB.

The ten earth system models included in the database are:

1. Community Atmosphere Model version 5 (CAM5)

2. Aerosol Two-dimensional bin module for foRmation and Aging Simulation (CAM-ATRAS)

3. Georgia Institute of Technology-Goddard Global Ozone Chemistry Aerosol Radiation and Transport model (GEOS-GOCART)

4. GEOS-Chem model (GEOS-Chem)

5. Tracer Model (TM5)

6. Oslo chemistry-transport model (OsloCTM3)

7. European Centre for Medium-Range Weather Forecast - Integrated Forecasting20 System model (ECMWF-IFS) run in the Copernicus Atmosphere Monitoring Service configuration

8. Global general circulation model ECHAM6 with the SALSA module (ECHAM6.3-SALSA2.0)

9. CAM5.3-Oslo model (CAM-OSLO)

10. Goddard Earth Observing System with the MERRA Aerosol Reanalysis (GEOS-MERRAero)
