New Publication Supports IPY

ESRL scientists have coauthored a paper published in the March 2007 issue of the Journal of Atmospheric and Oceanic Technology; its findings will serve as a basis for studying moisture variability in the Arctic. The paper describes the results of the North Slope of Alaska Arctic Winter Radiometric Experiment that was conducted at the Atmospheric Radiation Measurement Program's (ARM) "Great White" field site near Barrow, Alaska between 9 March and 9 April 2004. The manuscript is titled Analysis of Radiosonde and Ground-Based Remotely Sensed PWV Data from the 2004 North Slope of Alaska Arctic Winter Radiometric Experiment. [1.4MB PDF]

Nowhere on Earth is the impact of humidity on radiative transfer and climate feedback mechanisms more important than at the Earth's poles. Paradoxically, there is a dearth of information about moisture variability in these regions, and ESRL scientists are taking steps to reduce this uncertainty during the International Polar Year (IPY). Their approach is based on findings reported in this recently published article.

The science supporting this research article increases our understanding of the dynamics and impacts of the polar atmosphere as it relates to our climate. It is part of NOAA's Mission Goal to "understand climate variability and change to enhance society's ability to plan and respond."
