-> Aerosol Comparisons between Observations and Models



4th AEROCOM workshop

(held at Oslo, Norway, June 15-17, 2005)

This document contains presentations and posters of the AEROCOM workshop at Oslo in June 2005. Contributions are bundled by topic:

  1. The WORKSHOP INFO outlines the program and lists names of the workshop participants
  2. The OVERVIEW section introduces the ACCENT initiative and workshop goals.
  3. The WHERE WE ARE section contains diagnostical summary presentations about aerosol modules in global modeling
  4. The HOW TO USE THE WEB gives instructions on how to use the web diagnosis and evaluation tool

  1. The VERTICAL DISTRIBUTION section reviews capabilities to measure and simulate the vertical distribution of aerosol
  2. The AEROSOL FORCING section presents simulated aerosol impacts on the energy balance of the Earth- Atmosphere-System (radiative forcing). Simulations of different aerosol modules are compared and initial efforts are explored, where the aerosol forcing is more tied to observational evidence
  3. The MODULE DEVELOPMENT section addresses various new developments in aerosol global modeling
  4. The INDIRECT EFFECT addresses progress in understanding and quantifying aerosol indirect effects with the help of sensitivity studies and observational evidence from remote sensing
  5. The HUMIDIFICATION section explores model differences for aerosol water and for aerosol humidification and its impact on aerosol optical properties
  6. The AEROSOL PRODUCTS section present summaries and useful results from modeling and from model/data synergy for the general atmospheric science community

  1. The POSTERS section presents an AeroCom overview poster, compares details on simulated aerosol optical properties in component modeling, introduces concepts on investigating aerosol-cloud interactions and presents first results from a new effort to derive aerosol (direct) forcing by combining global fields of the median model with AERONET data.
  2. The SOURCES inventories of aerosol emission data for the years 2000 and 1750 (pre-industrial conditions) – in support of model sensitivities studies
