• Measure up and downwelling radiation at Davis to Baseline Surface Radiation Network (BSRN) standards ;
• Evaluate forecast performance at the stations and Wilkins Aerodrome;

Under Consideration
• extra sonde deployments, say up to 4/day, during the intensive measurement campaigns (need to plan now for budget staffing and consumubles, ozonesondes?); and
• radiosonde campaigns from the RSV Aurora Australis and/or the RV Investigator during the intensive measurement campaigns (is this covered by MARCUS)?.
• Ozonesondes.

Global Integrated Polar Prediction System• Global: International effort and poles have
global influences• Integrated: Interconnection between systems
(weather, climate, biological chemical etc) andintegrated (research, observations andservices)
• Polar prediction will be central Three time scales
• Short-term prediction (hours to seasonal)• Medium-term predictability (seasonal to
decadal)• Long-term projection of ice mass balance and
sea level (centuries)
GIPPS

Talk outline

Scott Carpentier is planning to contribute to the Societal and Economic Research Applications (SERA) aspect of
the YOPP.
Phil Reid is a member of the PPP steering committee and is supervising two projects on:
• ACCESS S sea ice evaluation (Laura Davies); and • Assessment/verification of ACCESS G in high latitudes with consideration for improved polar

we consider undertaking some permanent improvements to our Antarctic obs program and align their installation with PPP timelines, such as:
Improve the Macca and Davis upper air programs from GUAN to GRUAN (ie reference site – see attached email);
Install C&V sensors at all 4 stations (improves aviation ops (soon to be recommended by the Met Authority audit of Antarctic aviation services), aligned with OSS reduces

as well as temporarily:
commit extra sonde deployments, say up to 4/day, during the intensive measurement campaigns (could be for a 2 month period but has yet to firmed up); and
consider radiosonde campaigns from the RSV Aurora Australis and/or the RV Investigator during the intensive measurement campaigns.

The reasons for engaging
Ceilometers. The most useful data for us would be if the raw, vertically resolved backscatter ratio profiles could be saved. We would then perform our own cloud-detection analysis and also could look at aerosols and the structure of the clouds, based on the backscatter profiles.
Radiometers: it could be appropriate for Macquarie and or e.g. Davis to become a GRUAN site one day? Having the range of ozonesonde launches, radiometers, ceilometer as well as the standard radiosondes would all be beneficial .

Planned Observations – on site projects
Antarctic Clouds and Radiation Experiment (ACRE) :
• one year of continuous cloud, aerosol, and precipitation measurements at Macquarie Island (March 2016-March 2017) and at Davis station (2018). (BoM 95GHzCloud radar, AAD cloud and aerosol backscatter lidar and Uni of Canterbury ceilometer)
Macquarie Island Clouds and Radiation Experiment (MICRE)
• deploy a suite of cloud, aerosol, precipitation, and radiation in-situ measurements for two years at Macquarie Island (March 2016-March 2018). (US DOE ARM, BoM and AAD) )

Research into use and value of forecasts
• How do we do value the forecast?
• Forecast validation?
• Valuing the present international investment/return on investment could help develop a more sustainable model for Antarctic weather service delivery (less multiplication of effort through more cooperation.
