Overview
JCOMM in situ Observations Programme Support Centre October 2016
Argo is doing very well, …
IMPLEMENTATION• New design & targets: Global Argo = ~3800 floats• Atlantic Ocean optimal – deploy the excess in the Southern Ocean• Indian Ocean optimal• Pacific Ocean lightly over populated but clusters of old floats developing• Southern Ocean half implemented (improving) – strong seasonal bias for
RT data.
DATA FLOW• Optimize real-time distribution and delays• Challenge to re-process data files in delayed-mode (68% achieved)
INSTRUMENTATION• Float reliability keeps progressing
Executive Summary
JCOMM in situ Observations Programme Support Centre October 2016
Global Argo DesignTarget = ~3800 floats and optimal coverage, double density in Marginal Seas
JCOMM in situ Observations Programme Support Centre October 2016
Implementation – Activity
• Global array optimal (quantitatively) – on light decrease
• Atlantic Ocean optimal• Indian Ocean optimal• Pacific Ocean lightly over populated (WBC and Equatorial pilot projects)• Southern Ocean half implemented (improving)
Performance Indicators
JCOMM in situ Observations Programme Support Centre October 2016
Implementation – Intensity of deployments
• Global array deployments optimal – send excess to Southern Ocean
• Atlantic Ocean 25% over seeding (may not be required)• Pacific Ocean optimal• Indian Ocean optimal• Southern Ocean optimal (to be sustained)
Key Performance Indicators
JCOMM in situ Observations Programme Support Centre October 2016
Implementation – Data Spatial CoverageMonthly
• Global: good. To review metric and target (too conservative)• Atlantic Ocean - good • Pacific Ocean - very good.• Indian Ocean - good• Southern Ocean – poor (seasonal bias with real-time data and
deployments)

Biogeochemical Argo
JCOMM in situ Observations Programme Support Centre October 2016
Biogeochemical Argo needs to double the effort to reach its target and implement the full package (6 sensors) on all floats
IMPLEMENTATION• Activity stabilizing at 30%• Intensity of deployments 45% to be doubled
DATA FLOW• Optimize real-time distribution and delays, in cooperation with existing
Argo National Data Centres
INSTRUMENTATION• Sensor diversity progressing (data availability by sensor to be checked)• But 45% of the network is Oxygen only
