Subscriptions are available for AMSR-E, MODIS, and NISE data. Subscriptions apply only to future data as they are delivered to NSIDC; they cannot be used to receive data already in NSIDC's archive. This option is convenient if you require new data for a specific region as they are ingested into NSIDC's data archive, but you do not want to actively search and order data files each time. Based on your preference, NSIDC will either push new data to your local server via File Transfer Protocol (FTP) or will stage data on our FTP site for you to pull. Subscriptions can also be bundled on a weekly basis or whatever you prefer if you do not want to receive e-mail notifications each time a data file is ingested into NSIDC's archive. Please indicate this preference in the subscription form linked at the end of this page.
This page explains the basic information NSIDC needs to process your subscription request. We encourage you to read these sections carefully before entering your information in the subscription request form, linked at the end of this page.

Please provide your name, address, organization, e-mail address, affiliation type, and category.
Method of data delivery:
FTP Push: Data files are sent to your local server via FTP as soon as they are available.
FTP Pull: Data files are staged on NSIDC's FTP site for you to pull at your convenience. You have three days (72 hours) to retreive your data before files are automatically deleted.
Custom message: After you establish a subscription with us, our system sends you an e-mail message whenever data are pushed to you or staged on our FTP server. Most of the e-mail content is information generated by the sysem and, unfortunately cannot be changed. The subject line says "ECS Notification"; however, you can provide us with a unique message that you want to appear in the body of the e-mail message (see the USERSTRING in the example below), to help you better identify the purpose of the subscription. Please provide your unique message in the "Custom Message" area of the subscription form.
Sample e-mail notification from an FTP Push order:

From: CM SHARED (CM Code Delivery) <cmshared@n0ins02u.ecs.nasa.gov>

Please provide the following information if you select the "FTP Push" delivery option.
Local host name: Indicate the domain name or numerical IP address where the data should be sent. Example: "servername.colorado.edu"
Local directory: Provide the full directory path where the data will be pushed. This directory should have "write" permission for a successful FTP transfer, and should already exist before you request a subscription. Also please ensure you have adequate disk space for your anticipated subscription (see Data Volumes.)
Local user name: Account name to access your host. Please call NSIDC User Services (+1 303-492-2468) to provide your user name and password. You can also send us this information by e-mail, but be aware that this method is less secure.
EOS Data Gateway account name: If you previously ordered data from the EOS Data Gateway and you have an account there, please indicate your account login name. (No passwords are required.) If you do not have an EOS Data Gateway account, you must create one. Go to the EOS Data Gateway and follow the link to "Become a Registered User."
Data set title or ID: Please indicate the data set title or short name (ID). If you are unsure of these, please consult the following data summaries:
Data set version: Please indicate the version number you prefer to receive. Algorithms are continually improved, as limitations become apparent in early versions of data. As a new algorithm becomes available, a new version of data is released. Users are encouraged to work with the latest version available (the highest version number). Refer to the following pages for version numbers. (NISE data are version 1.)
Also specify whether you want to change to a new version as it becomes available, or continue to receive an earlier version until it is no longer available.
Geographic coordinates: Enter the approximate geographic coordinates of your study area. Data will not be subsetted upon delivery! This information is only used to identify data files that correspond to your study area, and to trigger a subscription for those files. You will receive the full data files.
Other special restrictions: Please indicate other criteria for your subscription. Each AMSR-E, MODIS, and NISE file contains metadata that indicates the level of quality, percentage of cloud cover, percentage of missing data, and many other variables, specific to that file. For example, if you indicate you want files with less than 75% cloud cover, only files that meet this criteria will be included in the subscription. Experienced users may recognize some of the most commonly used quality indicators:
QAPercentMissingData
ScienceQualityFlag ("Passed", "Failed", "Being Investigated", "Not Investigated", "Inferred Passed", "Inferred Failed", "Suspect", or "Hold.")
These are helpful, for example, if you only want data files with the ScienceQualityFlag set to "Passed." Please indicate this in the subscription request form. You can also indicate your preferred temporal coverage, but subscriptions are primarily used to send you new data as they become available.
Start and expiration dates of subscription: Please indicate how long you want the subscription to last, not the temporal coverage of the data.
