NOAA PMEL TPOS 2026 Nino 3.4 Saildrone 1033

Project: NOAA PMEL Institution: NOAA PMEL InfoURL: saildrone.com; pmel.noaa.gov Source URL: (local files) NOAA PMEL TPOS 2026 Nino 3.4 Saildrone 1033 Unknown tabular digital data Seattle, WA, USA ERDDAP, version 2.30.0, at NOAA/PMEL https://data.pmel.noaa.gov/pmel/erddap/tabledap/sd1033_tpos_2026.html https://data.pmel.noaa.gov/pmel/erddap/tabledap/sd1033_tpos_2026.graph NOAA PMEL This mission is part of a project titled "Uncrewed Surface Vehicles (USV) integrated within the Tropical Pacific Observing System (TPOS) - TPOS Equatorial Pacific Experiment (TEPEX) Process Studies Embedded Within Backbone Monitoring". It is, in addition, a regional contribution to the SUN Fleet (Surface UNcrewed Fleet), which has recently been endorsed as an emerging network of the Global Ocean Observing System (GOOS). Two of the four saildrones have a primary objective of observing the eastern edge of the western equatorial Pacific warm pool; the other two saildrones have a primary objective of observing frontal characteristics within the Nino 3.4 domain, with particular attention to the upwelling zone at 0, 140W. Each pair includes an ASVCO2 for providing biogeochemical observations to the Surface Ocean CO2 Observing Network (SOCONET). Both of these regions are targeted for TEPEX field campaigns by NOAA's Climate Variability and Predictability (CVP) Program. In February 2026, however, NOAA released an El Nino Watch, which was upgraded to an El Nino Advisory in May 2026, with a prediction of a very strong El Nino during November-January that would rank among the largest El Nino events in the historical record. Thus with the eastern edge of the warm pool located near 0, 140W prior to the mission launch, all four drones will target zonal and meridional fronts within the Nino 3.4 region (defined as the 5N-5S equatorial band between 170W and 120W), with a focus on the 155W and 140W Tropical Atmosphere/Ocean (TAO) mooring lines. In particular, one saildrone pair will perform large-scale meridional transects along the 155W TAO line, while the other pair will perform a transect along the 140W TAO mooring line. The two pairs will then meet on the equator during their zonal equatorial-band transects, at which point they will return to 0, 140W as a cluster of 4 drones. Traveling together, the cluster of USV will form roving oceanic- and atmospheric mesonets that resolve processes with mesoscale and sub-mesoscale variability, i.e., processes which are often unresolved by satellite and model products, and other in situ observing networks. In this way, the TPOS-2026 USV mission will provide information about the large-scale, meso-scale and sub-mesoscale frontal variability and processes associated with this strengthening El Nino.
