Providing ocean satellite data for the Arctic and Antarctic

ICESat-2 Hack Week

Submitted by pwadmin on Tue, 02/18/2020 - 10:01

Apply now to attend the ICESat-2 Hack Week, June 15-19, 2020, on the University of Washington campus in Seattle. There will be five days focused on open source tools to analyze and visualize ICESat-2 data for cryospheric applications. Applications are welcomed from participants at any career stage and level of technical ability. Application deadline: April 3, 2020.

Matchup Satellite and Argo Float Data

Submitted by pwadmin on Mon, 02/17/2020 - 13:31
This R exercise matches up in-situ and satellite data from an ERDDAP server. The exercise demonstrates the R tabledap function, using rxtracto to extract satellite data coincident with the in-situ data, using rxtracto_3D to extract a satellite data grid for a rectangular area, using rerddap to retrieve information about a dataset, producing xy scatter plots and producing satellite data maps and overlaying in-situ data.

New Sea Ice Pressure Ridge Sail Height Product Available

sea ice pressure ridge sail heightA new Sea Ice Pressure Ridge Sail Height product from NOAA is now available in the PolarWatch ERDDAP. Sail height data is derived from high-resolution airborne imagery acquired during NASA's annual Operation IceBridge campaigns in the Arctic (2010-2018).  Pressure ridges impact mass, energy, and momentum budgets of sea-ice cover and present an obstacle to transportation through icy waters.

Sail height data is derived from high-resolution airborne imagery acquired during NASA's annual Operation IceBridge campaigns in the Arctic (2010-2018).  Pressure ridges impact mass, energy, and momentum budgets of sea-ice cover and present an obstacle to transportation through icy waters. Quantifying ridge characteristics is important for understanding total sea-ice mass and for improving sea-ice dynamics in high-resolution models.
