Python wrapper for sending and receiving requests to Met Office Beta Data Services (BDS). This module requires webcoverageservice which can be installed from https://github.com/met-office-lab/ogc-web-services

To validate the requests an API key is needed, which must be registered with BDS. A key can be received by registering with Met Office DataPoint and following the link to "Your DataPoint API key". Currently, this gives you access to DataPoint data only. Contact the BDS team at the Met Office to have this key registered to get access the BDS data.

Requests can be made through WCS1 or WCS2 requests with the WCS1Requester and WCS2Requester classes. These classes both include methods for the basic request types:

• getCapabilities()
• describeCoverage()
• getCoverage() - Note, arguments differ between WCS1 and WCS2.

WCS2Requester also includes:

• describeCoverageCollection()

Example use:

import betadataservices as bds

bds.available_model_feeds()

EGloEGRR
UKPPBEST
UKPPNOW
EURO4
GlobEGRR

req = bds.WCS2Requester(api_key="your-datapoint-api-key-1234",
                        model_feed="UKPPBEST")
# Print out all available coverages.
req.getCapabilities()
