Saildrone Data Availability

Realtime (transmitted) Saildrone data from TPOS missions are available from LAS, ERDDAP, and as direct NetCDF downloads, which leverage ERDDAP services. Pages describing each mode of access can be found below, as well as examples from LAS and ERDDAP.

A full description of data accessibility through LAS (PMEL's Live Access Server) can be found on our LAS page.  Details of ERDDAP's data display and delivery can be found on our ERDDAP page.

OCS TPOS Direct Downloads

A list of downloadable NetCDF files from each mission and drone is available below. These files were downloaded directly from ERDDAP, repackaged to an even time grid, rebuilt with light QC and metadata edits, and retitled.

SD-PMEL-TPOS-2018-01**:

SD-PMEL-TPOS-2019-01**:

** Note: All variables are now present in the direct downloads for the 2019 mission, re-released 10/12/2021 with minor metadata corrections. With this update, missing realtime records were in-filled using averaged delayed-mode data for GPS, Wind, SWR, LWR, AT, RH, and the primary SST variable, with a data mode variable provided to distinguish between these sources. Data quality codes indicate where light, manual QC and/or gross error thresholds were applied to data spikes. 

Saildrone Carbon Data

Data collected by the PMEL Carbon Group on the OCS TPOS Saildrone missions are available on our Partner's Data webpage, or via this direct NCEI link. These data are recovered post-mission and require the application of quality control measures, so the most recent missions may not be available immediately.
