ADMLC have now added links to the Scientific Model Evaluation of dense gas DISpersion models (SMEDIS) data (SMEDIS | ADMLC) and accompanying information (including explanatory text, and links to a summary paper and two peer reviewed papers). ADMLC would love to hear from you if you have accessed this data – let us know how this dataset will be of benefit to you in the blog comments or email us at admlc@phe.gov.uk.
