Modeling Aerosol Nucleation Toon, Owen B.; Klein, Kari; Gamblin, Brandy; [2003]; 2 pp.; In English Contract(s)/Grant(s): NGT2-52264; No Copyright; Avail: CASI; A01, Hardcopy The goal of this work has been to understand how nitric acid condenses on cirrus ice cloud particles by analyzing data obtained during the SAGE III Ozone Loss and Validation Experiment (SOLVE) research mission based out of Kiruna, Sweden. Ms. Gamblin simultaneously analyzed gas phase nitric acid data along with particulate NO, data, particulate, vapor and gas-phase water data from several different instruments, particle size data, which included surface area and volume measurements, ozone concentration data as well as temperature, pressure and GPS coordinates of the sampled air parcel. All parameters where held constant with only one allowed to vary in order to determine what controls the extent to which nitric acid will condensation on ice. In addition, this data was compared to theoretical values of nitric acid condensation on ice based upon recent laboratory data. Comparison of these two data sets shows the field data does not agree with what is expected in the laboratory at comparable temperatures and nitric acid pressures. The most significant difference is that surface coverages in the atmosphere were found to be elevated relative to surface coverages measured in the laboratory. The results of this study were accepted for publication by Geophysical Research Letters.

The Battlescale Forecast Model (BFM) forecast fields of the surface meteorological parameters were used as background data. By this method, temperature and dew point temperature could be nowcasted well. The major reason for this is that the BFM forecasting calculation could provide good background fields of surface temperature and dew point temperature. Surface horizontal wind vector fields were really improved by the nowcasting calculation. The BFM forecast calculation alone could not produce reliable surface wind vector fields, but by combining the forecast data with observation, much more reliable wind field could be obtained than what would be determined by the BFM alone.

20030034728 NASA Goddard Space Flight Center, Greenbelt, MD, USA The Retrospective Iterated Analysis Scheme for Nonlinear Chaotic Dynamics Todling, Ricardo; July 11, 2002; 12 pp.; In English; Original contains color illustrations; No Copyright; Avail: CASI; A03, Hardcopy Atmospheric data assimilation is the name scientists give to the techniques of blending atmospheric observations with atmospheric model results to obtain an accurate idea of what the atmosphere looks like at any given time. Because two pieces of information are used, observations and model results, the outcomes of data assimilation procedure should be better than what one would get by using one of these two pieces of information alone. There is a number of different mathematical techniques that fall under the data assimilation jargon. In theory most these techniques accomplish about the same thing. In practice, however, slight differences in the approaches amount to faster algorithms in some cases, more economical algorithms in other cases, and even give better overall results in yet some other cases because of practical uncertainties not accounted for by theory. Therefore, the key is to find the most adequate data assimilation procedure for the problem in hand. In our Data Assimilation group we have been doing extensive research to try and find just such data assimilation procedure. One promising possibility is what we call retrospective iterated analysis (RIA) scheme. This procedure has recently been implemented and studied in the context of a very large data assimilation system built to help predict and study weather and climate. Although the results from that study suggest that the RIA scheme produces quite reasonable results, a complete evaluation of the scheme is very difficult due to the complexity of that problem. The present work steps back a little bit and studies the behavior of the RIA scheme in the context of a small problem. The problem is small enough to allow full assessment of the quality of the RIA scheme, but it still has some of the complexity found in nature, namely, its chaotic-type behavior. We find that the RIA performs very well for this small but still complex problem which is a result that seconds the results of our early studies.

The inventory update is to include all emission sources in the State that were identified in the Commission’s 1998 report, Historical and Forecasted Greenhouse Gas Emissions Inventories for California. This report, Inventory of California Greenhouse Gas Emissions and Sinks: 1990-1999, presents the Commission’s preliminary estimates of emissions and carbon sinks from 1990 to 1999. As Senate Bill 1771 requires, the report includes emissions of greenhouse gases and compares California’s emissions with the emissions from other states and nations. Limited information was available to allow a complete and thorough analysis and discussion of the impact of air quality and energy policies and programs on greenhouse gas emissions.

N.; 1996; 20 pp. Report No.(s): PB2003-102674; ARM-TR-003; No Copyright; Avail: CASI; A03, Hardcopy Broadband solar radiometer data collected at the U.S. Department of Energy’s Atmospheric Radiation Measurement (ARM) Southern Great Plains (SGP) Central Facility during the ARM Enhanced Shortwave Experiment (ARESE) exhibits inconsistencies and inter-calibration offsets. This report examines these problems, and in some cases, suggests error sources and possible solutions. The data discussed here covers the period from September 28, 1995, through October 30, 1995. Prior to that, the Baseline Surface Radiation Network (BSRN) radiometer data were not being logged for about 2 and one half weeks. This problem was not rectified until we inquired about the data for September 27, 1995, in support of an ARESE analysis. Most of the following discussion is based on 5-minute averages of the data. Site reports state that on October 13, 1995, the BSRN total shortwave (SW) pyranometer was changed to a newly calibrated one; therefore, much of the analysis 140
