  We have helped create the Total Carbon Column 
  Observing Network (TCCON) to measure the distribution 
  of greenhouse gases across the globe. This activity was 
  organized in partnership with the OCO satellite program 
  and is now being used as the validation network for the 
  Japanese GOSATsatellite.

Total Carbon Column Observing Network

TCCON is a network of ground-based Fourier Transform Spectrometers recording direct solar spectra in the near-infrared spectral region. From these spectra, accurate and precise column-averaged abundance of CO2, CH4, N2O, HF, CO, H2O, and HDO are retrieved.

TCCON provides an essential validation resource for the Sciamachy and GOSAT satellites.

NASA's Orbiting Carbon Observatory satellite failed to reach orbit after its 1:55 a.m. PST liftoff Feb. 24, 2009 from California's Vandenberg Air Force Base.

Preliminary indications are that the fairing on the Taurus XL launch vehicle failed to separate. The fairing is a clamshell structure that encapsulates the satellite as it travels through the atmosphere.

As of 12/9/09 ... The House-Senate Conference Committee has passed a FY 2010 budget for NASA. The Conference Committee Report includes the following specific direction with respect to an OCO reflight ... stay tuned!
