Scenarios

Each LASSO “scenario” is somewhat unique in terms of how it approaches a particular meteorological regime. This entails focused modeling around a particular suite of ARM measurements in conjunction with an overall scientific theme. Because of this, the data formats and bundle browser interfaces differ by scenario.

Data bundles are available for shallow convection days at the Southern Great Plains (SGP) atmospheric observatory during the period 2015–2019.

The Cloud, Aerosol, and Complex Terrain Interactions (CACTI) field campaign is the focus of the second LASSO scenario, generally referred to as the LASSO-CACTI scenario. The LASSO-CACTI datastream consists of a library of mesoscale and large-eddy simulations located near Córdoba, Argentina, from selected case dates between October 2018 through March 2019.

Marine clouds, such as those observed at ARM’s Eastern North Atlantic (ENA) atmospheric observatory, are unique from continental clouds because of the more uniform water surface and shallow boundary–layer characteristics. The LASSO-ENA scenario contains simulations for the Azores region, where the ENA is located. 

Considerations are ongoing for future scenario development. Post suggestions in the LASSO Discourse forum or contact lasso@arm.gov if you have ideas on what should be done next. Concepts around recent ARM campaigns or sites are of particular interest, such as the Bankhead National Forest atmospheric observatory.
