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.

TAD: Toolsets for Airborne Data

Use NASA's Toolsets for Airborne Data (TAD) web application for accessing the data sets.


DLR Falcon flight tracks

DLR Falcon data

Data from DLR Falcon aircraft conducted from 2001 to 2012.

Altitude range: Surface to 12 km.


HIPPO flight tracks

NCAR / NSF HIPPO data

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.


C-130 flight tracks

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.


START08 flight tracks

NCAR / NSF START08 data

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.
