Task Team on Measurement Schedules and Associated Instrument-type RequirementsUnder the auspices of the WG-GRUAN the scheduling Task Team was established to:
•Provide guidance on the ideal suite of measurement sampling requirements for the network addressing the primary GRUAN objectives:
◦climate monitoring – to confirm the requirements for regular measurements (in terms of capability and schedule) that will provide a reliable and consistent measurement of decadal trends in the key climate variables,
◦ satellite calibration and validation – focusing primarily on providing long-term support for the satellite community, particularly in the area of data ‘gap-filling’ to help establish consistency and comparability between individual satellite records.
•Liase with GRUAN sites and groups planning mesoscale studies to review what the potential impact of such studies, with their own specific objectives and scheduling requirement, will be on the long-term monitoring objectives of GRUAN.
•Gather information on sampling strategies from the peer-reviewed literature, GRUAN documentation, and currently unpublished studies of which the team is aware;
•Identify suitable measurement and model data sets for sampling studies;
•Define sampling strategy assessment activities, with the aim of linking these to the current and future research activities of the team members and other groups;
•Report to the WG-GRUAN on all above duties
