ERDDAP > Out-Of-Date Datasets

The outOfDate index is a simplistic measure of how out-of-date a dataset is: <0: unexpectedly from the future(!), <1: up-to-date, >=1: out-of-date, >=2: very out-of-date. For out-of-date datasets, there is presumably a problem with the data source, so ERDDAP is unable to access data from more recent time points.

Options

You can add tabledap-like constraints to requests to this web page, for example,
https://polarwatch.noaa.gov/erddap/outOfDateDatasets.html?&outOfDate>=0.5 . Usually, the parameter values in the URL (the parts after '=' signs) must be properly percent encoded (external link)

: all characters other than A-Za-z0-9_-!.~'()* must be encoded as %HH, where HH is the 2 digit hexadecimal value of the character, for example, a space becomes %20. Characters above #127 must be converted to UTF-8 bytes, then each UTF-8 byte must be percent encoded (ask a programmer for help). There are websites that percent encode and decode for you (external link)

The information in the table above is also available in other file formats (.csv, .htmlTable, .itx, .json, .jsonlCSV1, .jsonlCSV, .jsonlKVP, .mat, .nc, .nccsv, .tsv, .xhtml) via a RESTful web service.
