Meteorology

Working Group

Mission/Vision

To define a consistent set of instruments and data processing procedures to measure meteorology variables across the LTAR network.

Objectives

  • To make the first near real-time common observations from LTAR available to the public from an NAL repository
  • To provide data from all sites to users in a common format with the same data definitions
  • To ensure comparability of common observatory data across the network. To the extent scientifically feasible and appropriate, instruments of equivalent quality (precision, accuracy) will be used with common methods.
  • To accommodate varying levels of IT capabilities and build skills at the LTAR sites. For example, developing a clearinghouse for code and operating procedures to share with all sites.
  • To maintain continuity for observations that extend historical records.
  • To develop a foundation for subsequent common observatory data (hydrology, eddy flux…)

Activities

List activities that are currently happening or that are planned for this working group.
Next steps (from Archbold meeting):
  • Settle on measurement interval, averaging and reporting interval
  • Finalize meteorology metadata developed by Jeff Campbell
  • Develop standard data logger programs with initial QA checks
  • Develop secondary QA/QC programs
  • Finalize data table formats for transmission to NAL
  • Begin transmission of legacy data and its documentation to NAL
  • Guidance on maintenance tasks and frequency

Accomplishments

  • A set of standard operating procedures (SOPs) and sampling methodology has been developed
  • The Meteorology Working Group has developed a recommended set of variables to measure
    • LTAR Met Report-July-11-2015.docx 
    • List of recommended variable
      • Air temperature/ relative humidity
      • Wind speed and direction
      • Precipitation
      • Phenology camera
      • Barometric pressure
      • Short and long-wave radiation (incoming and reflected if combined in a single instrument)
      • Photosynthetically-active radiation (PAR) incoming
    • Transmission of the recommended variables to NAL
  • A list of recommended instrumentation, typically from at least two vendors, to make recommended measurements
