NASA Scientific and Technical Aerospace Reports

The Terrestrial and Planetary Environments Team at Marshall Space Flight Center (MSFC) proposes to facilitate
validation, documentation, and adoption of updated Range Reference Atmospheres (RRAs). This viewgraph presentation
describes the plan, focusing on seven tasks: 1) Document data sources; 2) Document analytical models; 3) Document data
processing procedures; 4) Compare updates to 1983 versions; 5) Compile written documentation; 6) Obtain approval for final
volumes; 7) Publish new RRA datasets/documents.

The Atmospheric Radiation Measurement (ARM) Program’s Single Column Model (SCM) working group conducted its
intercomparison study of midlatitude summertime continental convection using the July 1995 Intensive Operational Period
(IOP) data set (Ghan et al. 2000). Only one cloud-resolving model (CRM) participated in the study. On the other hand, several
CRMs participated in the GEWEX (Global Energy and Water-cycle Experiment) Cloud System Study (GCSS) Working Group
4’s intercomparison study of tropical deep convection (Krueger and Lazarus 1998; Redelsperger et al. 2000). Both groups
decided to have a joint intercomparison project to maximize the resources and advance our understanding of midlatitude
continental convection. This joint project compares the cloud-resolving and single-column simulations of summertime
continental cumulus convection observed at the Southern Great Plains (SGP) Cloud and Radiation Testbed (CART) site during
the ARM Summer 1997 IOP. This paper reports the findings and results of cloud-resolving simulations, while Cederwall et
al. (2000) reports the SCM part of the project. Seven CRMs are participating in this project.

Climate Change and California

Climate change represents a significant risk to California as a result of a warming and increasingly variable climate. The
signs of a global warming trend continue to become more evident and much of the scientific debate is now focused on expected
rates at which future changes will occur. Rising temperatures and sea levels, and changes in hydrological systems are threats
to California’s economy, public health, and environment. In 1988, the California Legislature recognized that climate change
could adversely affect the state and called for an assessment of impacts and identification of potential strategies. Since then
California has inventoried its greenhouse gas emissions, improved energy efficiency and conservation, created a voluntary
greenhouse gas registry, established ambitious goals for renewable energy, and is now preparing regulations to achieve
reductions in greenhouse gas emissions from motor vehicles. While California has been a leader in addressing climate change,
more can be done to better prepare for an uncertain climate future and improve the resiliency of the state’s economy. Taking
appropriate steps to address risks posed by climate change can help insure a more sustainable future and benefit the state’s
citizenry and natural and economic resources.

Global Climate Change and California: Potential Implications for Ecosystems, Health, and the Economy

This project is the most detailed study ever undertaken on the potential effect of climate change on California. This work
examines a broad array of potentially affected sectors as well as the interactions between climate change and increased
population, economic growth, and technological change. It considers a wide range of climate change scenarios, ranging from
warmer and much wetter to warmer and much drier. Most climate models estimate that precipitation will increase. Climate
change is likely to have substantial impacts on California. The location of natural vegetation will change dramatically.
Productivity could increase under wetter conditions and biodiversity could be reduced under drier conditions. The combined
