Identifying and Estimating Biases between XBT and Argo Observations Using Satellite Altimetry
Publisher: American Meteorological Society
Abstract: A methodology is developed to identify and estimate systematic biases between expendable bathythermograph (XBT) and Argo observations using satellite altimetry. Pseudoclimatological fields of isotherm depth are computed ...
Direct Evidence of a Changing Fall-Rate Bias in XBTs Manufactured during 1986–2008
Publisher: American Meteorological Society
Abstract: his paper presents direct evidence of systematic depth errors consistent with a fall-rate bias in 52 temperature profiles collected using expendable bathythermographs (XBTs). The profiles were collected using the same ...
Effects of a Warm Oceanic Feature on Hurricane Opal
Publisher: American Meteorological Society
Abstract: On 4 October 1995, Hurricane Opal deepened from 965 to 916 hPa in the Gulf of Mexico over a 14-h period upon encountering a warm core ring (WCR) in the ocean shed by the Loop Current during an upper-level atmospheric trough ...
Surface Ocean Mixing Inferred from Different Multisatellite Altimetry Measurements
Publisher: American Meteorological Society
Abstract: Two sea surface height (SSH) anomaly fields distributed by Archiving, Validation, and Interpretation of Satellite Oceanographic (AVISO) Altimetry are evaluated in terms of the effects that they produce on mixing. One SSH ...
Objective Detection of Oceanic Eddies and the Agulhas Leakage
Publisher: American Meteorological Society
Abstract: esoscale oceanic eddies are routinely detected from instantaneous velocities derived from satellite altimetry data. While simple to implement, this approach often gives spurious results and hides true material transport. ...
