NSIDC DAAC Hands-on Tutorial: Discover, Access, and Harmonize Arctic Remote Sensing Data during the 2019 AGU Fall Meeting

The NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) will be presenting a hands-on tutorial during the 2019 AGU Fall Meeting, hosted by the ARCUS Arctic Community Meeting Space. This tutorial will demonstrate our data discovery, access, subsetting services, and how to utilize basic open source resources to harmonize and analyze data across different remote sensing products.

Our data services team will be presenting this tutorial as a series of Python-based Jupyter Notebooks, focusing on sea ice height and ice surface temperature data from NASA’s ICESat-2 and MODIS missions, respectively, to characterize Arctic sea ice. No coding experience or computing prerequisites are required, though some familiarity with Python and Jupyter Notebooks is recommended.

Registration for this tutorial will close on Tuesday, December 10th, so please be sure to sign up to ensure a seat: https://forms.gle/48AiCNPdxbzoUDBH7

When: Wednesday, December 11th, 2:00 – 3:30 PST

Hotel Nikko, Room: Monterrey I
222 Mason St, San Francisco, CA 94102

We look forward to seeing you in San Francisco!ICESat-2 Freeboard This composite image is a measurement of Arctic sea ice freeboard taken by ICESat-2’s instrument from data acquired between 1 to 30 November 2018.

ICESat-2 Data Now Available at NSIDC DAAC

Featured

The first data sets from NASA’s Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) are now available from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). These data sets provide backscatter profiles; geolocated photon data; atmospheric layer characteristics; and geolocated surface elevations for land ice, sea ice, vegetation and land, and inland water.

The ICESat-2 web page provides an overview of the satellite mission and information on specific data sets, including those currently available and ones scheduled for future release.

Data access options for ICESat-2 data include direct download through HTTPS, but more advanced options for searching, customization, and data delivery can also be achieved through the following methods:

OpenAltimetry provides advanced discovery, processing, and visualization for both ICESat and ICESat-2 data.

Earthdata Search provides access to both ICESat and ICESat-2 data, with advanced search and order options. Here users have the option to customize their data, including reformatting; reprojection; and subsetting by spatial coverage, temporal coverage, and parameter.

Data set subscription is an option available for users who require the latest data delivered on a regular basis. As data are ingested at NSIDC DAAC, our subscription service will automatically send a subscriber data files that match their specifications. This can be done through email or through the Secure Copy Protocol (SCP), where NSIDC DAAC will send data directly to an SCP-enabled server. If the email delivery option is selected, users can choose to apply customizations, such as subsetting, reformatting, and reprojection, to their data files.

All access options are available on each ICESat-2 data set landing page in the “Data Downloads” tab.

Upcoming Earthdata Webinar – NASA Operation IceBridge: Come Discover a Decade of Polar Data

NASA’s Operation IceBridge airborne mission has flown over 700 flights through some of the most stunning regions of the Arctic and Antarctic. Join us to learn how to discover and access data that “bridges” the gap between the ICESat and ICESat-2 missions.

When: Wednesday, July 25, 2018 at 2pm EDT (UTC/GMT-4).
