This study examines the transport of chemical species to the upper troposphere/lower stratosphere (UTLS) by Typhoon Mireille (1991). We follow an integrated research approach,...

The key assumption underlying convection parameterizations is that rising plumes develop in a horizontally homogeneous environment. With this in mind, we investigate the impact...

The penultimate deglaciation (PDG, similar to 138-128 thousand years before present, hereafter ka) is the transition from the penultimate glacial maximum (PGM) to the Last...

This report is part of a series prepared for the Materials Research Project of the NCAR Scientific Balloon Facility in order to extend the reliability and capabilities of...

Natural carbon sinks currently absorb approximately half of the anthropogenic CO2 emitted by fossil fuel burning, cement production and land-use change. However, this airborne...

Ground-based observations of the OH(9-4, 8-3, 6-2, 5-1, and 3-0) band airglows over Xinglong, China (40°24'N, 117°35'E) from December 2011 to 2014 are used to calculate...

As known from previous studies on the solar quiet (Sq) variation of the geomagnetic field, the strength and pattern of ionospheric dynamo currents change significantly from day...

El Nino/Southern Oscillation (ENSO) has far reaching global climatic impacts and so extending useful ENSO forecasts would have great societal benefit. However, one key variable...

A 9-year database of sunlit E region electron density altitude profiles (N-e(z)) measured by the Sondrestrom incoherent scatter radar (ISR) has been partitioned over a parameter...

This report reproduces the introspective review meeting about operational lessons learned from the Line Islands experiment that took place during March and April 1967....

A model intercomparison activity was inspired by the large suite of observations of atmospheric composition made during the International Polar Year (2008) in the Arctic. Nine...

Isocyanic acid (HNCO), a product of some combustion processes, can potentially have negative human health effects. While gas phase HNCO loss processes are slow, HNCO loss in the...

The relationship between Indian Ocean sea surface temperature and the transition of El Niño events into either La Niña or El Niño-Southern Oscillation neutral conditions is...

The Arctic radiation balance is strongly affected by clouds and surface albedo. Prior work has identified Arctic cloud liquid water path (LWP) and surface radiative flux biases...

Permafrost soils contain enormous amounts of organic carbon whose stability is contingent on remaining frozen. With future warming, these soils may release carbon to the...

Globally averaged surface air temperatures in some decades show rapid increases (accelerated warming decades), and in other decades there is no warming trend (hiatus decades). A...

Adjustments for the wind-induced undercatch of snowfall measurements use transfer functions to account for the expected reduction of the collection efficiency with increasing...

An airflow trajectory analysis was carried out based on an idealized numerical simulation of the nocturnal 9 February 1993 equatorial oceanic squall line observed over the...

Aircraft measurements of the ubiquitous marine stratocumulus cloud type, with over 3000 km of in situ data from the Pacific during the Cloud System Evolution in the Trades...

Each year, the Computational & Information Systems Laboratory (CISL) conducts a survey of its current and recent user community to gather a number of metrics about the...
