Linked Environments for Atmospheric Discovery II (LEAD II)

Tags:
Overview
LEAD II is a follow-on to the successful Linked Environments for Atmospheric Discovery NSF funded large-scale ITR. LEAD II carries the vision of LEAD forward into new areas as it explores research challenges in hybrid computing and in the manipulation and use of weather data in non-weather applications.

The LEAD II project utilizes the LDM system to ingest gigabytes of publicly-available weather data on a daily basis, for use in meteorological analysis, metadata collection, and workflow systems research.  The products ingested include NEXRAD Level 2, ADAS, Rapid Update Cycle (RUC), and North American Mesoscale (NAM) data.  The NAM data has resolutions of 12KM and 40KM.

At this year's Cloud Futures workshop PhD student Eran Chinthaka Withana presented results in deploying and running a WRF workflow on Azure.   The work employs the Trident Scientific Workflow Workbench to deploy the workflow, and uses Azure VM roles to execute the workflow tasks.  It utilizes a tool called Sigiri developed in the Data To Insight Center that aids in the deployment.

"The WRF workflow (including WPS, WRF, ARWPost, and GRADS) is notoriously difficult to build and run on a new platform. This demonstration shows successful execution to a cloud resource, but also successful deployment of a full workflow on a Windows platform.  It's great work that to our knowledge has not been done before," said Dr. Beth Plale, Director of the Data To Insight Center.

The Cloud Futures workshop series brings together thought leaders from academia, industry and government to discuss the role of cloud computing across a variety of research and educational areas - including computer science, earth sciences, healthcare, humanities, life sciences, and social sciences.

Cloud computing is a resource of significant value to com- putational science, but has proven itself to be not imme- diately realizable by the researcher. The cloud providers that offer a Platform-as-a-Service (PaaS) platform should, in theory, offer a sound alternative to infrastructure-as-a- service as it could be easier to take advantage of for com- putational science kinds of problems.

Data Catalog Data Catalog harvests data product metadata from distributed THREDDS catalogs into an XMC Cat instance. The metadata (including data product location) is then available to applications via the XMC Cat API. Data catalog metadata harvesting employs a shared nothing ingest pipeline to allow for the indexing of large catalogs such as NEXRADIII and has indexed of over 17 thousand collections and 2 million files.

Understanding the effects of boundary layer and synoptic meteorology on new particle formation based on WRF simulations and measurements in Southern Indiana The purpose of this study is to investigate the relationship between the occurrence and intensity of new particle formation at the local and regional scale and i) the evolution of boundary layer properties and ii) the presence of specific synoptic conditions. Although progress has been made in understanding new particle formation dynamics, the role of boundary layer conditions and synoptic systems as limiting variables for nucleation has not been clearly quantified. Our analysis couples...
