Water Vapor

B. Demoz (UMBC) — Monthly CFH radiosondes have been launched year-round since 2012 to obtain profiles of water vapor, temperature, pressure, and winds from the surface to about 30km. Although not with regularity — these CFH measurements extend back to 2005. A majority of these soundings are accompanied with an ECC Ozonesonde and RS92 and/or RS41. Frequent coordinated launches with the NOAA-NWS Sterling test site are made to investigate spatial homogeneity and sampling coordination with Satellite overpass. Nearly all launches are within an hour of satellite overpass times and unique for Cal-Val opportunity.

A. Murk (U. Bern) — Volume mixing ratio profiles (20 to 70 km).

J. T. Sullivan (GSFC), L. Twigg (SSAI), and G. Sumnicht (SSAI) — The Aerosol and Temperature Lidar (AT Lidar) has been rebuilt, and now includes water vapor to ~15 km, temperature in the troposphere using rotational Raman backscatter, stratospheric temperature up to ~80 km, and aerosol parameters using elastic and Raman backscatter up to ~35 km. As a mobile intercomparator, it has participated in intercomparisons at Mauna Loa from November 2012–August 2013, January 2014 & 2015 and November 2015. Data up to 2015 is archived in the name of the previous PI – McGee.

J. T. Sullivan (GSFC), L. Twigg (SSAI), and G. Sumnicht (SSAI) — The STROZ lidar retrieves ozone vertical profiles in the stratosphere from 10 to 50 km. Temperature to ~80 km and aerosols (at 355 nm) to 35 km also are measured. The instrument has also been modified to measure water vapor from near the ground to ~15 km. As a mobile intercomparator, it participated in ozone intercomparisons in May 2015. The 2015 data is archived in the name of the previous PI – McGee.

R. Sica (Univ. of Western Ontario) — Raman water vapor measurements since 1999. Significant data gaps in 2008–2010.  No data in 2010 due to instrument re-location. After replacing major components, operations restarted October 2017. Awaiting funding decision for operations beyond April 2018.

N. Kämpfer (U. Bern) — Profiles (~35 – 70 km) obtained with a water vapor radiometer on a daily basis from August 2013 to February 2015.

N. Kämpfer (U. Bern) – Profiles (~35 – 70 km) obtained with a water vapor radiometer on a daily basis from June 2011 to March 2013.

J. T. Sullivan (GSFC), G. Sumnicht (SSAI), and L. Twigg (SSAI) — The Aerosol and Temperature Lidar (AT Lidar) has been rebuilt, and now includes water vapor to ~15 km, temperature in the troposphere using rotational Raman backscatter, stratospheric temperature up to ~80 km, and aerosol parameters using elastic and Raman backscatter up to ~35 km. When not participating in campaigns, the instrument conducts measurements at the NASA Goddard Space Flight Center in Greenbelt, MD. The AT lidar participated in the WAVES 2006, 2007, 2008 and 2009 campaigns conducted in Beltsville, MD. Data through 2009 is archived in the name of the previous PI – McGee.

Temperature to ~80 km and aerosols (at 355 nm) to 35 km also are measured. The instrument has also been modified to measure water vapor from near the ground to ~15 km. As a mobile intercomparator, it has participated in ozone intercomparisons at the Table Mountain Facility February/March 1992, February/March 1997, June 2004, June 2005, October 2009 (MOHAVE), and February–March 2011. Data through 2011 is archived in the name of the previous PI – McGee.

As a mobile intercomparator, it has participated in ozone intercomparisons at Lauder October–December 1992, March–October 1994, April 1995, September–December 2001, April 2002, June–July 2011, and April 2012. Data through 2012 is archived in the name of the previous PI – McGee.
