SNOWIE Data Submission Instructions
Dataset Documentation ("Readme") Guidelines
The documentation (i.e., the "Readme" file) that accompanies each project data set is as important as the data itself. This information permits collaborators and other analysts to understand any limitations or special characteristics of the data that may impact its use. Data set documentation should accompany all data set submissions, including both preliminary and final. The following outline and content is recommended and should be adhered to as closely as possible to make the documentation consistent across all data sets.
Data Set Documentation/Readme Outline:
Title: This should match the data set name
Author(s):
- Name(s) of PI and all co-PIs. For DOI purposes, indicate lead author and list all authors to be included.
- Complete mailing address, telephone/facsimile numbers
- E-mail address of PIs, and web address (if applicable)
- Similar contact information for data questions (if different than above)
1.0 Data Set Overview:
- Introduction or abstract
- Time period covered by the data
- Physical location (including lat/lon/elev) of the measurement or platform
- Data source if applicable (e.g., for operational data include agency)
- Any web address references (i.e., additional documentation such as Project web site)
2.0 Instrument Description:
- Brief text (i.e., 1-2 paragraphs) describing the instrument with references
- Figures (or links), if applicable
- Table of specifications (i.e., accuracy, precision, frequency, resolution, etc.)
3.0 Data Collection and Processing:
- Description of data collection
- Description of derived parameters and processing techniques used
- Description of quality assurance and control procedures
- Data intercomparisons, if applicable
4.0 Data Format:
- Data file structure and file naming conventions (e.g., column delimited ASCII, NetCDF, GIF, JPEG, etc.)
- Data format and layout (i.e., description of header/data records, sample records)
- List of parameters with units, sampling intervals, frequency, range
- Data version number and date
- Description of flags, codes used in the data, and definitions (i.e., good, questionable, missing, estimated, etc.)
5.0 Data Remarks:
- PI's assessment of the data (i.e., disclaimers, instrument problems, quality issues, etc.)
- Missing data periods
- Software compatibility (i.e., list of existing software to view/manipulate the data)
6.0 References:
- List of documents cited in this data set description. Please provide links for any publications, if available.

Upload Schedule
The schedule is being adjusted to accommodate the concurrent C-130 activities. Please refer to the frequently updated Work Schedule.
PDF version is available here.
SNOWIE Data Submission Instructions
An initial master list of all SNOWIE international datasets (with links) has been compiled to provide easy access to all operational and research SNOWIE datasets. This list will form the SNOWIE Long-term Data Archive at NCAR Earth Observing Laboratory where datasets are grouped and sorted by category (i.e., radar, satellite, etc.) and platform. Please review this list to verify that your dataset(s) are properly named, with the appropriate authors identified. Email any corrections, additions, or deletions directly to eol-archive@ucar.edu. If you already have your datasets available on-line elsewhere, please email the link(s) or FTP access information.
To submit your dataset(s) and documentation to the SNOWIE Long-term Data Archive, see the anonymous FTP instructions below. For users without Internet access, or if your dataset(s) are too large to FTP (e.g., 250GB or larger), please contact eol-archive@ucar.edu. In these cases, users can submit their data on a USB drive to the shipping address below. If you have a large number of files to FTP, please tar or zip your files by day or what makes sense for your dataset.
It is critical that submitted datasets are accompanied by sufficient documentation. The minimum required metadata is shown below after the FTP instructions. More detailed documentation guidelines can be found here.
Data Submission FTP Instructions for the SNOWIE Long-term Data Archive at NCAR/EOL:
FTP: ftp.eol.ucar.edu
Login: anonymous (No password required.)
cd /pub/data/incoming/snowie (NOTE: This command should be done all in one step.)
It is very important to send an email to eol-archive@ucar.edu once your file(s) have been FTPed. In your email and in your dataset readme file, please include the following minimum required information for your dataset(s):
- Dataset Title - The dataset title that will publicly appear in the data archive. EOL may modify for project consistency.
- Dataset Author(s) - List dataset authors. Indicate lead and corresponding authors. Include contact information.
- Time of Interest - Include begin and end dates (i.e., YYYY/MM/DD hh:mm:ss to YYYY/MM/DD hh:mm:ss).
- Area of Interest - Include GeoLocation information (latitude/longitude box) (e.g., 40.00 to 45.50; -95.37 to -110.00).
- Data Frequency - Frequency of data collection (5 minute, hourly, continuous, etc.).
- Data Spatial Type - ISO metadata SpatialRepresentation (vector, grid, textTable, tin, stereoModel, video, etc.) which describes how the geographic nature of the data is represented.
- General Dataset Description - Short description of this dataset.
- File Names - List names of files transferred.
- Data restrictions - Indicate if dataset needs to be restricted. Password protection is available for a dataset upon request. A dataset will NOT be password protected unless requested at the time of submission or as specified in this project's Data Policy. If password protection is requested, you will receive a project-specific "user ID" and "password." If you require additional security, please contact eol-archive@ucar.edu to request a unique "user ID" and "password" for your data.
- Digital Object Identifier (DOI) - Indicate if you would like for NCAR/EOL to generate a DOI for your dataset. If your dataset already has a DOI, please include that link in your email.
- GCMD Keywords - Please select keywords at least down to the "variable_level_1" level to support search and discovery of your dataset. Select keywords from the list at http://gcmdservices.gsfc.nasa.gov/static/kms/sciencekeywords/sciencekeywords.csv?ed_wiki_keywords_page
- Publications (Optional) - Please include a list of links to publications using this dataset, including "in press" and "submitted" publications, conference proceedings, theses, and reports. Submitted publications will be added to this project's publications list.
Thank you for providing data to the Long-term Data Archive at NCAR/EOL. Feel free to contact us with any questions or issues.
