ECHAM5-HAM precipitation and aerosol optical depth data

Introduction: These files contain data from ECHAM5.5-HAM2.0 model simulations. The Sundqvist stratiform cloud cover scheme has been used. The simulations are described in Grandey et al. (2013; doi:10.5194/acp-13-3177-2013) and Grandey et al. (2014; doi:10.1002/2014GL060958). These data are analysed in Grandey et al. (2014; 10.1002/2014GL060958). File size warning: These files are relatively large. File format: .nc is the extension for NetCDF format, a binary data format commonly used for climate model output data. These NetCDF files contain metadata which aid interpretation of the contents. The metadata and data can be explored using the free Panoply software tool (http://www.giss.nasa.gov/tools/panoply/ [28-Aug-2015]). File naming convention: - HAM_B011 refers to the control simulation. - HAM_B013 refers to the NoConvScav simulation, in which wet scavenging by convective precipitation has been turned off. - *_apr_*.nc contain precipitation data. - *_aod_*.nc contain aerosol optical depth data. - *_aoddry_* contain dry aerosol optical depth data. Contributions and acknowledgments: Philip Stier and Till M. Wagner contributed to the experimental design. P.S. contributed to the configuration of ECHAM5-HAM. P.S., T.M.W. and Anisha Gururaj contributed towards the analysis in Grandey et al. (2014). The simulations were performed while B.S.G. was supported by a UK Natural Environment Research Council (NERC) DPhil studentship. The analysis was performed while B.S.G. was funded by the Singapore National Research Foundation (NRF) through the Singapore-MIT Alliance for Research and Technology (SMART) Center for Environmental Sensing and Modeling (CENSAM).
