The Western Wildfire Experiment for Cloud Chemistry, Aerosol Absorption and Nitrogen (WE-CAN) study aims to better understand the chemistry of wildfire smoke.


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.

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.

Remote Sensing of Electrification, Lightning, and Mesoscale/Microscale Processes with Adaptive Ground Observations (RELAMPAGO) 

RELAMPAGO will form a key part of an observation network that will elucidate the tight connections between the land surface, complex terrain, convective development, and the production of severe weather. Through its unique configuration of atmospheric profiling and remote sensing capabilities, understanding of processes that impact prediction of societal hazards will be improved. RELAMPAGO will be based in Argentina from 1 June 2018 to 15 April 2019.

New Online Training Lesson:
Instrumentation and Measurement of Atmospheric Pressure

This lesson provides information about current science and technologies for measuring atmosphere pressure. The lesson begins by reviewing the key physical laws governing atmospheric pressure, including Dalton's Law of Partial Pressures. Then, it explores typical requirements and uncertainty parameters related to atmospheric pressure sensors and provides details about the components of pressure sensors, including fluidic, mechanical, and electronic transducers. The lesson is part of the Instrumentation and Measurement of Atmospheric Parameters course series.
