The CHEESEHEAD field campaign will address long-standing puzzles regarding the role of atmospheric boundary-layer responses to scales of spatial heterogeneity in surface-atmosphere heat and water exchanges.


EOL is beginning development of a novel 5-cm Airborne Phased Array Radar (APAR) with dual-Doppler and dual-polarization capabilities to be operational on the NSF/NCAR C-130 aircraft.


A series of meteorological instrumentation and measurements training modules for undergraduate and graduate education is being produced by the EOL, Millersville University, and The COMET Program.


The past 100 years has been characterized by synergism between societal needs for weather observations and the needs of fundamental meteorological research into atmospheric processes.

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.


Organization of Tropical East Pacific Convection (OTREC) 

OTREC will help determine the large-scale environmental factors that control convection over tropical oceans. The HIAPER Cloud Radar measurements of precipitation in conjunction with the AVAPS dropsonde measurements will deepen our knowledge of East Pacific convection and aid in the interpretation of satellite observations. OTREC will deploy the NSF/NCAR GV to Costa Rica from 5 August to 30 September 2019.

HAIS Instrumentation Announcement

Due to programmatic changes within the National Science Foundation (NSF), as of 1 August 2018 the Time-of-Flight Aerosol Mass Spectrometer (ToF-AMS) and Quantum Cascade Laser Spectrometer (QCLS) HAIS instruments are no longer requestable through the NSF Lower Atmosphere Observing Facilities Deployment Pool. Please contact the RAF science and instrumentation group lead for more information on accessing these facilities.
