As observational estimates were analyzed in different categories based on data processing and measurement methods, similar a priori approach could be applied to GCMs considering the shared components between models [49,

On 18–20 July , a workshop was held at the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland that focused on understanding possible reasons for this difference, through an examination of the instrument designs, calibration approaches, and.

In the intercomparison project " Models and Measurements II " (Park et al., ), many CTMs (both 2-D Models and measurements intercomparison II book 3-D) were used to simulate age.

The results of this exercise are discussed in detail in. The activity and publication of this “Models and Measurements Intercomparison II (MM II)” during the three-year period starting in November of was made possible by the unselfish hard work of many international modeling groups and atmospheric scientists.

Altogether, 28 atmospheric simulation models were used for model intercomparisons. Eight chemical transport models participate in a model intercomparison study for East Asia, MICS-Asia II. This paper analyzes calculated results for particulate matter of sulfate, nitrate and ammonium through comparisons with each other and with monthly measurements at EANET (the acid deposition monitoring network in East Asia) and daily measurements at Fukue, by: HEPP A-II model-measurement intercomparison pr oject: EPP.

The focus of the present paper is the Jack Rabbit II chlorine trials and one of the drivers for the project was a model inter-comparison study published in that compared hazard estimates from six widely used dense-gas dispersion models for three chlorine railcar incidents in the USA (Hanna et al., ).

Results are presented from an intercomparison of single‐column and cloud‐resolving model simulations of a deep, multilayered, mixed‐phase cloud system observed during the Atmospheric Radiation Measurement (ARM) Mixed‐Phase Arctic Cloud Experiment.

We compare simulations from three high-top (with upper lid above km) and five medium-top (with upper lid around 80 km) atmospheric models with observations of odd nitrogen (NOx = NO + NO2), temperature, and carbon monoxide from seven satellite instruments (ACE-FTS on SciSat, GOMOS, MIPAS, and SCIAMACHY on Envisat, MLS on Aura, SABER on TIMED.

The need to understand differences among general circulation model projections of CO 2 ‐induced climatic change has motivated the present study, which provides an intercomparison and interpretation of climate feedback processes in 19 atmospheric general circulation models.

This intercomparison uses sea surface temperature change as a surrogate for climate change.

This paper evaluates the current status of global modeling of the organic aerosol (OA) in the troposphere and analyzes the differences between models as well as between models and observations. Thirty-one global chemistry transport models (CTMs) and general circulation models (GCMs) have participated in this intercomparison, in the framework of AeroCom phase II.

The simulation of OA varies. The lack of highly accurate flux observations from within the atmosphere has made it necessary to rely on line‐by‐line model results for evaluating model accuracy. As the intercomparison project has proceeded, the number of models agreeing more closely with the line‐by‐line results has increased as the understanding of the various.

Introduction. At a combined Working Group on Coupled Models (WGCM) and Global Analysis Interpretation and Modeling (GAIM) meeting in Victoria, B.C., Canada, it was recognized that the proliferation of various model intercomparison projects (termed "MIPs") has generated a certain degree of confusion in respective research communities.

As a first step in helping everyone keep better track. Model-retrieved data residuals were found to be around 5% (dBZ scale, or 20%–25% linear scale) for the reflectivity (Z), and most of the time fall within the range of uncertainty expected with radar measurements and with the data retrieval procedure (±1 dBZ).

For other integral parameters, differences were comparable to estimated. The two models used in the intercomparison study, a SORTIE-PPA [46,47] variant and LANDIS-II with NECN succession [87,], are intended to directly address these model shortcomings.

It is obvious that one high precision laboratory calibration is a much bigger challenge for the accuracy of spectroradiometers than several multiple.
