MashMyData

The mutual comparison of diverse datasets is a fundamental cornerstone of environmental science. Processes of numerical model validation, data assimilation, quality control and “ground truthing” all rely on the ability to bring datasets together and assess their relative value. The MashMyData project (a NERC-funded collaboration between the ReSC and STFC) will allow numerical model, in situ and satellite datasets to be combined and compared in a new web interface (see screenshot), reducing technical barriers to common intercomparison tasks. Users will be able to access data that are securely held in the British Atmospheric Data Centre and the Earth System Grid; this presents a strong technical challenge but we have recently made excellent progress towards achieving this new capability, which will make great strides towards “unlocking” vast data resources. In addition, users will be able to upload their own data into the system, which will be stored securely “in the cloud” and made available for intercomparison on the web.
