Webinars and Tutorials


After the virtual 2020 Joint ARM User Facility/Atmospheric System Research (ASR) Principal Investigators Meeting, ARM started to conduct a series of webinars on topics of interest to the user community. ARM sent out a survey to the community after the 2020 joint meeting to gauge which topics were of interest. Notable topics included:

  • field campaign processes
  • introduction to the Large-Eddy Simulation (LES) ARM Symbiotic Simulation and Observation (LASSO) activity
  • ARM computer clusters and development tools
  • ARM Data Discovery
  • open-source software repositories
  • the ARM Diagnostics package and Energy Exascale Earth System Model (E3SM) single-column model.

This page includes documents and videos from completed webinars and tutorials, in addition to related materials.

Large-Eddy Simulation (LES) ARM Symbiotic Simulation and Observation (LASSO) Tutorial, May 2021

The LASSO activity generated LES ensembles for five years’ worth of shallow convection cases (2015–2019) at ARM’s Southern Great Plains (SGP) atmospheric observatory. These simulations, combined with a suite of relevant observations, skill scores, and diagnostics, are packaged into “data bundles” that can be used for many purposes, such as providing data for cloud studies or for providing prepackaged data sets to simplify student interaction with atmospheric observations and model data.

During the LASSO tutorial, participants learned more about the SGP shallow convection scenario, how they may access the data for their research or classwork, and how they could use the LASSO evaluation software on their own model output. Part 1 of the tutorial focused on the LES methodology used in LASSO and how to obtain LASSO data, Part 2 focused on the observation suite included in the LASSO bundles, and Part 3 focused on the LASSO workflow. Read more about the tutorial.

ARM Data Discovery Webinar, March 2021

ARM Data Discovery is where you can access and order data from ARM’s nearly 30-year-old archive. During this webinar, led by ARM Data Center staff, participants learned how to effectively use new Data Discovery features, including the guided search, location search, and advanced keyword search, to find data. They also learned how to review additional details about the data, see their past orders, and generate citations. Read more about the tutorial.
