Groups working on:

Non-satellite actions:

B4: Expand surface and in situ monitoring of trace gas composition and aerosol properties. Invite Vincent?

C3: General Improvements to in situ Data Products for all ECVs

F1.3: Increase temporal resolution of surface air temperature, soil moisture and precipitation to capture both climate and human-induced changes and extremes.

Satellite Actions

B1.3 3. Better align the satellite FRM program to the reference tier of tiered networks and enhance / expand FRM to fill gaps in satellite cal/val

B1.5: Establish a long-term space-based reference calibration system to enhance the quality and traceability of earth observations

D4.1: Improve access to co-located satellite and reference quality in situ observations, as well as tools for evaluation purposes. This facility will use data from reference networks and FRM programs for a broad range of ECVs for calibration/validation of satellite programs.

Caterina and panel members

A1.1: Undertake an assessment of current levels of funding support for global in situ networks delivering relevant in situ ECV data, including cal/val measurements, and identify those in situ networks with immediate or short-term problems around adequacy and sustainability of funding

GCOS Sec. will provide a table to start assessment of in-situ networks.
