DATA REQUESTS (UP TO 1 GB)

A direct, or synchronous, data request will return the files that belong to the requested dataset(s) that cover the requested timespan. These requests are known as synchronous because the files will be downloaded as soon as the compressed tar package is ready. Authentication is not necessary for this type of download.

If the package requested is over 1 GB (compressed), you could either do an Asynchronous request (up to 50 GB) or reduce your request.

Certain applications require a Streamed download to retrieve a single CEF file immediately.

For CEF files, new CEF files are created by extracting the data from the original files for the timespan given and concatenating them as directed in the request. The file format (CEF, CDF or ISTP) can be specified, as can the time interval that the delivered files will cover (e.g., hourly, daily, etc). For non-CEF source files, the files delivered are direct copies of the files stored at the archive.

The package delivered will be a gzipped tarball (note: extension is .tgz) by default.

There are two types of data requests:

which depend on the value of the RETRIEVAL_TYPE parameter: RETRIEVAL_TYPE=PRODUCT for data requests and RETRIEVAL_TYPE=HEADER for header requests (parameter and values are case insensitive).

 

PRODUCT REQUESTS

A synchronous data retrieval has a limit of 1GB (compressed).

The Base

The details of the request need to be built on the following base:

https://csa.esac.esa.int/csa-sl-tap/data?

Then add the RETRIEVAL_TYPE, DATASET_IDSTART_DATE and END_DATE details, which are mandatory:

PARAMETER NAME(S)

DESCRIPTION

MANDATORY?

POSSIBLE VALUES

RETRIEVAL_TYPE

Type of retrieval. PRODUCT (Cluster data file) or HEADER

YES

PRODUCT or HEADER

DATASET_ID

Unique identifier of the dataset whose data we want to retrieve.
It can appear more than once, and can contain wild cards ('*')

YES

Any of the Cluster datasets.

START_DATE

Start time of the time range that the retrieved files should cover.

YES

ISO time format: 'yyyy-MM-ddTHH:mm:ssZ'

END_DATE

End time of the time range that the retrieved files should cover.

YES

ISO time format: 'yyyy-MM-ddTHH:mm:ssZ'

If the dates aren't included, the request will be accepted but the dates will default to the start and end of the Cluster mission.

The optional parameters are listed here:

PARAMETER NAME(S)

DESCRIPTION

MANDATORY?

POSSIBLE VALUES

DELIVERY_FORMAT

Delivery format, applicable only to CEF files. By default, CEF

NO

CEF, CDF, CDF_2_7 or CDF_ISTP

DELIVERY_INTERVAL

Specifies the delivery file interval in time. By default, "Daily"

NO

All, Daily, TenMin, Hourly, hourly3, hourly6, hourly12

FLAT

By default, FLAT=FALSE and files will be returned in a directory structure for each dataset ID. With FLAT=TRUE, all files will be returned in a single directory.

NO

FALSE or TRUE; 0 or 1

FORCEPACK

By default TRUE: package will be tarballed, then gzipped.

If FALSE, package is not tarballed, and a zip will download.

NO

TRUE or FALSE; 1 or 0

GZIP

By default, GZIP=FALSE and the files inside the package are not gzipped themselves; make GZIP=TRUE to have all the files within the package gzipped - good for large CEF files, and many programs can read gzipped ASCII files without gunzipping.

NO

FALSE or TRUE

INCLUDE_EMPTY

By default, INCLUDE_EMPTY=1 and if the files corresponding to the dataset requested are empty (they do not contain any records) they will be included in the delivery. Set this to 0 if the empty dataset files are not wanted.

NO

FALSE or TRUE; 0 or 1

INGESTED_SINCE

Only download files that have been ingested since a particular date.

NO

ISO time format: 'yyyy-MM-ddTHH:mm:ssZ'

MAX_FILE_SIZE

The size of the maximum amount of uncompressed data that can be downloaded in kB. If the query results in a delivery that exceeds the specified file size the user will receive an error message.

NO

A positive integer representing the maximum file size in kB

REF_DOC

By default, REF_DOC=1 and the files in the request are delivered WITH their reference document if available. Referenced documents are typically CAVEAT or SETTINGS data. Set this to 0 if the referenced files are not wanted.

NO

1 or 0
