In-Situ Measurements Group Instrument Development Projects

Instrument Development Projects:


  • NCAR is committed to fully support the university community in field experiments. This requires taking a long-term view on development and building instrumentation for the future. 
  • ACOM has a long history of providing reliable and high quality data and scientific expertise for in situ observational atmospheric chemistry.
  • ACOM’s instrumentation suite (CO, O3, CO2, CH4, N2O, NO, NO2, H2O, VOCs, actinic flux) remains among the most frequently requested for community field studies.
  • This instrument suite is in need of updating to enable ACOM to continue to serve the community at the highest level.
  • ACOM has received special funding from NSF and hired a Scientist to lead the development of a new, windgpod based CIMS instrument for the measurement of complex, oxygenated organics.
  • ACOM's NOx and O3 Measurements, Core Atmospheric Tracers and Engineering Support teams also plan to develop a wingpod based Photochchemical Tracer Package (ChemPod).
  • Wingpod instruments eliminate long inlet lines, which have proven poblematic for the measurement of highly reactive species such as complex organics, halogens, radicals, acids, and other "sticky" compounds.
  • Wingpod instruments free up cabin space (which for chemistry missions, and especially on the NSF/NCAR GV is always at a premuim) and enhance payload capabilities.
  • Modularizing the Core Atmospheric Tracer measurements for a large wing stores installation adds in situ air mass characteriziation payload to non-chemistry, remote sensing projects requesting the HIAPER Cloud Radar (HCR), without requiring additional cabin space.
