ERDDAP Data Server

PolarWatch maintains an ERDDAP server with a large collection of environmental datasets which provides the backbone for our data catalog. The ERDDAP data server provides a simple, consistent way to subset and download environmental datasets in common file formats with options to make graphs and maps. Access the data server directly or learn more about it through the following links.

New sea ice datasets added to PolarWatch
Apr 25, 2019

nsidc sea ice preview interfaceThe NOAA/NSIDC Climate Data Record of Passive Microwave Sea Ice Concentration, Version 3 and the near real-time version of the Climate Data Record datasets have been added to the PolarWatch catalog. These datasets provide long term science quality sea ice concentration records for the Arctic and Antarctic dating back to 1978.

SOCCOM Near-Realtime BGC-Argo data now on PW ERDDAP
Feb 21, 2019

soccom float mapSouthern Ocean Carbon and Climate Observations and Modeling (SOCCOM) BGC-Argo float data is now available on the PolarWatch ERDDAP. The SOCCOM project augments conventional Argo floats with biogeochemical sensors to measure carbon (pH), nutrients (nitrate), and oxygen. About 200 autonomous floats provide coverage over the Southern Ocean, with vertical coverage deep into the water column.

Visualizing a Decade of Change in the Arctic Sea Ice Cover AGU iPoster
Dec 19, 2018

Farrell_AGU_2018_Poster_Ice_graphicPolarWatch scientist Sinéad Farrell delivered an interactive poster on visualizing change in Arctic sea ice cover at AGU 2018. The poster highlights NOAA Lab for Satellite Altimetry sea ice data products showing variability in ice type and ice thickness over the last decade and shows some very early ICEsat-2 results.

Spring Satellite Data Workshop in Juneau
Sep 24, 2018

The next NOAA Ocean Satellite Data Course will be held in Juneau, Alaska, March 5-7, 2019. In this annual three-day course participants learn about ocean satellite data and how to easily obtain it. Participants gain hands on experience working with data of interest to them. The course provides scientists who are not regular users of satellite data with the tools they need to incorporate satellite data into their projects.
