Earth Observing Laboratory. A premier facility of the National Center for Atmospheric Research (NCAR) dedicated to advancing the observational science of the Earth's atmosphere and its interactions with the broader Earth system. It provides the scientific community with state-of-the-art observational facilities, field project support, and data services to investigate critical phenomena from severe weather to climate change. The laboratory operates under the auspices of the University Corporation for Atmospheric Research (UCAR) and is headquartered in Boulder, Colorado.

Overview

The core mission is to provide leadership and essential tools for conducting complex field campaigns across the globe, from the Arctic to the tropics. It manages a world-class fleet of mobile and fixed observing platforms that measure atmospheric parameters, supporting research into fundamental processes like convection, aerosol-cloud interactions, and boundary layer dynamics. By integrating advanced instrumentation with sophisticated logistics and data assimilation techniques, it enables transformative research that improves predictive models for weather forecasting and climate projection.

History and development

The laboratory was formally established in 2005 through a strategic reorganization within NCAR, consolidating several existing observational programs and facilities into a single entity. This consolidation built upon decades of expertise from legacy projects like the Atmospheric Technology Division and field campaigns such as the Fronts and Atlantic Storm-Track Experiment (FASTEX). Its creation was driven by the growing scientific need for integrated, large-scale observational studies to address grand challenges in Earth system science, a priority highlighted in reports by the U.S. National Research Council. Since its inception, it has been instrumental in major international projects like HIAPER Pole-to-Pole Observations (HIPPO) and the NSF-funded OWLeS project.

Major facilities and instruments

The laboratory's flagship facility is the NSF/NCAR Gulfstream V (GV), a high-altitude research aircraft also known as HIAPER, capable of operations up to 51,000 feet and equipped with suites for measuring trace gases, cloud microphysics, and aerosols. Other critical assets include the S-PolKa dual-polarization Doppler radar, a mobile sounding system for launching weather balloons, and the Integrated Surface Flux Facility for measuring turbulent fluxes. The facility also deploys an array of lidar systems, microwave radiometers, and autonomous unmanned aerial systems (UAS) for targeted observations in challenging environments.

Key research programs and discoveries

It has played a central role in numerous landmark field programs that have reshaped scientific understanding. The HIPPO campaign provided the first comprehensive, global, vertical profiles of greenhouse gases like carbon dioxide and methane, revolutionizing models of the global carbon cycle. The PLANET investigations and the Deep Convective Clouds and Chemistry (DC3) experiment yielded critical insights into how severe storms transport pollutants to the upper troposphere and lower stratosphere. Research using its facilities has also been pivotal in studying atmospheric rivers impacting California and orographic precipitation processes in regions like the Rocky Mountains.

Organizational structure and partnerships

The laboratory is structured into several technical and support groups, including the Research Aviation Facility, the Earth Observing Laboratory Field Projects & Outreach, and engineering divisions. It maintains deep collaborative ties with NASA, the National Oceanic and Atmospheric Administration (NOAA), and the U.S. Department of Energy through shared projects like the Atmospheric Radiation Measurement (ARM) program. Internationally, it partners with agencies such as the European Centre for Medium-Range Weather Forecasts (ECMWF) and research institutions across Asia and Europe for coordinated field campaigns.

Data management and accessibility

A fundamental principle is ensuring that observational data from its campaigns are curated, quality-controlled, and made freely available to the global research community. Data are archived and distributed through the NCAR Earth Observing Laboratory Data Archive, which complies with standards set by the World Meteorological Organization and the International Council for Science. The laboratory employs advanced cyberinfrastructure and collaborates with the UCAR Community Programs to facilitate data discovery and integration into community models like the Weather Research and Forecasting model (WRF), supporting open science and reproducible research.
