XBT

XBT data providers are under pressure

First XBT Science Workshop, July 2011, Melb

High-density XBT lines are:

typically quarterly;

Eddy-resolving

Impact of XBT data on forecast systems is much less than Argo (3% of data)

Potential value of repeated, eddy-resolving lines is significant

Should all operational GOV systems with-hold XBT data from high-density lines are use them for:

Independent verification; and

Inter-comparison?
