MOGREPS-UK SNS - Matching SNS name attribute to the description of data

Hello,

I have subscribed to the MOGREPS-UK SNS ARN (arn:aws:sns:eu-west-2:021908831235:aws-earth-mo-atmospheric-mogreps-uk-prd) and I am trying to determine the link between the data returned in the message and the [description of the data](https://www.metoffice.gov.uk/binaries/content/assets/metofficegovuk/pdf/data/mogreps-uk-aws-parameters-november-2019.pdf) from your website, referenced from the [Registry of Open Data on AWS](https://registry.opendata.aws/uk-met-office/).

For example, in the JSON data below there is a "Name" attribute of "lwe_thickness_of_graupel_and_hail_fall_amount", but I can't see this at all in description of the data. Can you help me with the link (lookup list or similar), or point me in the direction for how I can work this out, or correct me in my interpretation of the logic if I've misunderstood things?

Many thanks, Rob.

Start with the MOGREPS-UK SNS example in the issue, then compare its name attribute with the linked MOGREPS-UK AWS parameters PDF and the AWS Open Data registry entry. Done means providing or documenting a reliable mapping between the SNS name and the published data description, or correcting the interpretation if no direct mapping exists.
