   Marcia Baker
   
   Marcia Baker earned her bachelor's degree at Cornell University and her Ph.D.from the University of Washington, both in physics.While raising her three children she served part-time on the research faculty in Atmospheric Sciences and Geophysics (now Earth and Space Sciences).Since 1976 she has held an academic appointment in those departments and retired as Professor Emeritus in 2004.She and her husband Marshall have traveled widely and frequently in Europe in connection with short-term appointments at foreign universities and attendance at scientific meetings.Marcia was one of several faculty who organized and led a symposium on the nuclear arms race.She also organized and leads a group of faculty and graduate students who review science policy issues for the Union of Concerned Scientists.

   "Based on our current knowledge, it shouldn't exist," said Marcia Baker, a University of Washington professor of Earth and space sciences.She is one of six climate researchers who authored a Perspectives article in the Nov. 30 edition of the journal Science promoting an extensive effort to investigate the dilemma.
   
   Part of the problem is that many atmospheric scientists have dismissed the findings as erroneous because the current understanding of atmospheric conditions and cirrus clouds would make the water vapor anomaly impossible, Baker said.Yet a number of pieces of evidence published in peer-reviewed journals and presented at scientific meetings during the last six years have supported the finding.
   
   Clouds and particles in the atmosphere play a significant role in regulating the Earth's temperature because they help determine how much of the sun's heat and energy is reflected back into space and they trap outgoing radiation from the Earth's surface.Cirrus clouds also are important in regulating the distribution of water vapor, the most important greenhouse gas, in the upper troposphere.
   
   "We have thought our models of the formation and evolution of cirrus clouds are generally adequate in how they portray the role of cirrus clouds in regulating water vapor, but if the recent findings are accurate and high humidities are widespread, our assumptions could need significant adjustment," Baker said.
   
   "The point is to bring this to the more general science audience as a broad puzzle, but also to lay the groundwork for research to solve the puzzle," she said.

   It is possible the aerosols might have as-yet undiscovered properties that prevent crystals from forming in some conditions, or there could be some kind of coating on the aerosols that prevents ice from forming, Baker said.There also could be some undiscovered property of ice crystals that prevents them from growing in certain conditions.
   
   "There could be a different phase of ice at the temperatures and pressures in cirrus clouds that has a higher equilibrium for vapor," Baker said.
