In alignment with advice from public health professionals, both locally and globally, NCAR|UCAR is undertaking recommended protocols to reduce “community spread” of COVID-19 as a way to mitigate risks to our staff, their families, and the community. Together with the rest of the organization, EOL has implemented mandatory telework beginning Tuesday, March 17, at noon.

Celebrating Women in STEM

EOL's Adriana Bailey talks with CBS' Unstoppable about measuring the isotopic composition water vapor in clouds to detect where its previous path by using the NSF/NCAR HIAPER GV research aircraft. Watch video.


Officials Break Ground on EOL's Research Aviation Facility (RAF)

Construction starts this month on a major National Center for Atmospheric Research (NCAR) facility, funded by the National Science Foundation (NSF), that will support aircraft flown on scientific field projects worldwide, leading to new advances in weather, climate, and air quality research.

Officials with NCAR, NSF, and the University Corporation for Atmospheric Research (UCAR) broke ground on the $22 million construction project at the Rocky Mountain Metropolitan Airport in Broomfield on 14 February 2020. The new building — which replaces a dated, half-century-old structure at NCAR’s Research Aviation Facility — is expected to open its doors by the end of the year. Read more.



The MethaneAIR project, funded by the Environmental Defense Fund (EDF), will deploy the NSF/NCAR HIAPER GV aircraft to test a new airborne imaging spectrometer as part of the International Methane project. The primary goal of the program is to accurately measure emissions of CH4 from oil and gas production and processing facilities across the world, in order to define and track this major contribution to the rise of this greenhouse gas and pollutant in the global atmosphere.

NSF LAOF Request Process Improvement

As of 1 February 2020, PIs requesting access to the NSF LAOF for Small and Large Campaigns must submit their requests through PRESTO (Project Requests Online). PRESTO is a web-based, integrated documentation handling system that automates and streamlines the main aspects of the LAOF request process, specifically the submission of facility requests and EDOs, the preparation of feasibilities, and the distribution of review documentation.

Please visit Request Lower Atmosphere Observing Facilities and PRESTO Guidance for Submitting PIs webpages for more information.


New Educational Material: Instrumentation and Measurement of Cloud Hydrometeors and Airborne Particles

EOL is pleased to announce the publication of a new module, Instrumentation and Measurement of Cloud Hydrometeors and Airborne Particles. This module aids learners in developing a basic ability to conduct observational studies of cloud hydrometeors and aerosols or airborne particles.


UAS Workshop Final Report

The NCAR / EOL Community Workshop on Unmanned Aircraft Systems (UAS) for Atmospheric Research was held in February 2017 and brought together over 100 participants interested in the role of UAS in atmospheric science.  The Final Report is now available and contains recommendations that emphasize the need for wide-ranging community support and address topics such as expert teams and workshops, community platforms, dedicated instrumentation and platform validation opportunities, weather forecasting and support in working within the aviation regulatory framework.


C-RITE Workshop Final Report

The Community Workshop on Developing Requirements for In Situ and Remote-Sensing Capabilities in Convective and Turbulent Environments (C-RITE) was carried out by over 100 participants to assist the National Science Foundation in defining next-generation technologies and observing capabilities best suited for studying convection and turbulence in the atmosphere. The C-RITE Workshop Final Report is now available containing recommendations addressing improvements to existing facilities, urgently needed new facilities, and desired new observing systems.
