Description:
Goals:
This experiment was performed to assess the reactive uptake behavior of trans beta-IEPOX that was synthesized for the experiment. Different particle inorganic compositions (mainly ammonium sulfate or AS) and different particle water content were investigated. Particles are injected into the chamber as deliquesced droplets (through a wet wall denuder) and they stabilize to their equilibrium particle liquid water content depending on their hygroscopicity.
Summary:
Large organic aerosol (OA…

Description:
For RDA ERA5 monthly mean data prior to 1979, please see ds633.5:
ERA5 monthly mean back extension 1950-1978 (Preliminary version)
After many years of research and technical preparation, the production of a new ECMWF climate reanalysis to replace ERA-Interim is in progress. ERA5 is the fifth generation of ECMWF atmospheric reanalyses of the global climate, which started with the FGGE reanalyses produced in the 1980s, followed by ERA-15, ERA-40 and most recently ERA-Interim. ERA5 w…

For ancillary use only - not recommended as a primary research dataset. It has likely been superseded by newer and better datasets.
Description:
DS126.0 represents a dataset implemented and computed by NCAR's Data Support Section, and forms an essential
part of efforts undertaken in late 2004, early 2005, to produce an archive of selected segments of ERA-40 on a
standard transformation grid.
In this case, forty seven ERA-40 monthly mean surface and single level analysis
variables were transformed from a reduced N80 Gaussian grid to a 256 by 128 regular Gaussian grid. All fields were
transformed using routines fr…
