There is a more recent version of these data.
Version Summary
Changes for this version include:

  • The blowing snow frequency parameter based on the 1 Hz average backscatter data was renamed to low-rate blowing snow frequency and a high-rate blowing snow frequency parameter generated from 25 Hz backscatter data was added.

  • The grid size for the weekly product (ATL16) changed from 2° x 2° to a 3° latitude x 3° longitude for the global coverage and to a 1° latitude x 3° longitude for the polar coverage.

  • The grid size for the monthly product (ATL17) changed from 1° x 1° to a 1° latitude x 1° longitude for the global coverage and to a 0.5° latitude x 1.5° longitude for the polar coverage.

  • Gridded parameter minimum, maximum, and standard deviation values in addition to the average are written on each image and included in the data product.

Overview

This data set contains a gridded summary of monthly global cloud fraction, total column optical depth over the oceans, polar cloud fraction, blowing snow frequency, apparent surface reflectivity, and ground detection frequency.

How To

Many NSIDC data set web pages provide the ability to search and filter data with spatial and temporal contstraints using a map-based interface. This article outlines how to order NSIDC DAAC data using advanced searching and filtering. 
This guide will provide an overview of the altimetry measurements and data sets across the missions, as well as a guide for accessing the data through NASA Earthdata Search and programmatically using an Application Programming Interface (API).
  Data from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) can be accessed directly from our HTTPS file system or through our Application Programming Interface (API).
The following table describes the subsetting and reformatting services that are currently available for ICESat-2 data via the NASA Earthdata Search tool, along with
