Veronika Eyring - (DLR) Scientific Steering Group, CCMI
Tom Ryerson - (NOAA) Working group leader for in-situ aircraft measurements
This working group addresses the following tasks:
- Develop a methodology to evaluate global CCM simulations using integrated in-situ observations from research aircraft.
- Improve online access to observational datasets that have been evaluated for quality and formatted for consistency to facilitate model-data intercomparison studies.
- Develop diagnostics to identify composite datasets with climatological value and provide these formatted datasets to the community.
- Report analyses on the CCMI Observations for model evaluation.

Airborne data
NOAA ESRL Chemical Sciences Division data
NOAA WP-3D flights from chemically-instrumented field missions conducted from 1999 through 2010 in the contiguous United States and Alaska.
Altitude range: surface to 7 km.
NASA Tropospheric Chemistry data
NASA DC-8 and P-3B aircraft data from field missions conducted from 1987 through 2011.
Altitude range: Surface to 12 km (DC-8)
Surface to 7 km (P-3B).
Use NASA's Toolsets for Airborne Data (TAD) web application for accessing the data sets.
Data from DLR Falcon aircraft conducted from 2001 to 2012.
Altitude range: Surface to 12 km.
The HIPPO (HIAPER Pole-to-Pole Observations) study of the carbon cycle and greenhouse gases measured meteorology, atmospheric chemistry, and aerosol constituents along transects from approximately pole-to-pole over the Pacific Ocean using the NSF/NCAR GV aircraft. Five missions took place in different seasons from 2009 through 2011.
Altitude range: Surface to 15 km.
NCAR / NSF INTEX-B / Milagro data
The NSF/NCAR C-130 participated in two projects in the spring of 2006 in conjuction with NASA: INTEX-B based in Mexico City, and IMPEX based in Seattle, WA.
Altitude range: Surface to 8 km.
Stratosphere-Troposphere Analyses of Regional Transport (START08) studied the chemical and transport characteristics of the extratropical upper tropospheric and lower stratospheric region using the NSF/NCAR GV research aircraft. A total of 18 flights were conducted in the United States and Canada during April, May and June 2008.
Altitude range: Surface to 15 km.
