Physical Processes Linking Solar Radiation and Solar Variability with Global Climate Change

December 2003 SORCE Science Meeting Science Program Review!

The Earth Observer Jan/Feb 2004 Vol. 16, No. 1: "The Solar Radiation and Climate Experiment (SORCE) Science Team Holds its First Meeting Since Launch"

Thanks to everyone who attended/presented at the December 2003 SORCE Science Meeting. This EOS Solar Radiation and Climate Experiment (SORCE) meeting was our first science meeting since the January 25, 2003 launch and it was a great success! The meeting was devoted to our understanding of the physical processes that connect the Sun’s radiation and its variability to our terrestrial environment, including the processes involved with climate and ozone response to solar radiative forcing and the mechanisms that cause solar activity and radiation variations. The agenda consisted of both invited and contributed oral presentations and posters. Scientific Sessions were given on the following topics:

  • Solar Radiation - Status of Current Measurements
  • Climate Change Processes Involving Solar Radiation in the Troposphere
  • Global Change Processes Involving Solar Radiation in the Stratosphere
  • Processes and Evidence for Long-Term Irradiance Variations
  • Future Directions in Sun-Climate Research

Sonoma Valley Wine Tour: Saturday, Dec. 6, 12:30 p.m. – 5:00 p.m.
After a busy week of meetings, enjoy an afternoon tour of the local wineries that made Sonoma famous! This will be a special journey to the historic and family-owned wineries in the area. Jake’s Valley Wine Tours will pick our group up at The Lodge at Sonoma for a scenic drive up the valley to three unique wineries, where you will be treated to private tastings. Your winery hosts and tour guide will educate you on the world of wine and offer a behind the scenes glimpse. Friends and family are welcome on this special tour.

One of the stops will be at the Benziger Family Winery, where you will wander through a century-old ranch with farmhouse, tasting room, and art gallery. A tram will take you through the vineyards to the top of a hill crowned with an Acropolis temple. The view from the ridge top is breathtaking! In the tasting room you will be treated to their reserved wines and learn about their organic stewardship.

We will also visit Gundlach Bundschu, which is the oldest family winery in the country. They have been growing wine grapes for over 143 years! After a special outdoor tasting (weather permitting), we will go on a cave tour and discuss wood and the taste imparted on the wine. Gundlach Bundschu is best known for it Gewurztraminer and Bearitage wines. They grow sixteen different veritals and have won many gold medals.

Finally, we will visit the home site of the father of California viniculture, Count Agoston Harazity, which is known as Bartholomew Park Winery. This beautiful location has a 4000 case winery. The wines are exceptional and are made in the French style. This winery has a very unique history in that it has been used for many other things in its past, including a morgue, school, brothel, and a hospital. Within the building is a fascinating museum, which will take you back to the early days of viticulture.

Tickets: $75. Includes transportation, guided tour, and wine tastings.


December in Sonoma is wonderful, with cool mornings and evenings, and warm afternoons. The temperatures average a high of 60° F and a low of 37° F in early December. The key is to “layer” since you never can tell this time of year in California. Rain is common in December. The following website could be helpful to check before you pack -- (linked to Sonoma, CA local weather).
