Cooling of the mesosphere and lower thermosphere due to doubling of CO2
A new parameterization of infrared radiative transfer in the 15-lm CO2 band has been incorporated into the Spectral mesosphere/lower thermosphere model (SMLTM). The parameterization is applicable to calculations of heating rates above approximately 15 km for arbitrary vertical pro®les of the CO2 concentration corresponding to the surface mixing ratio in the range 150±720 ppm. The sensitivity of...
متن کاملTIMED Instruments
he Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics (TIMED) mission is providing a core set of measurements defi ning the basic states of the mesosphere and lower thermosphere/ionosphere (MLTI) region (approximately 60–180 km above the Earth’s surface) and its global energy balance. This article discusses the TIMED spacecraft’s suite of four remote sensing instruments designed to ob...
متن کاملVertical Transport and Photochemistry in the Terrestrial Mesosphere and Lower Thermosphere ( 50 - 120 km )
The coupled effects of kinetics, solar cycle flux variations and vertical transport on the distribution of long-lived hydrogen-carbon-oxygen compounds in the terrestrial mesosphere and lower thermosphere are studied using a one-dimensional eronomy model. The calculations account for the important chemical reactions and use rocket measurements of the solar flux at solar minimum and maximum. Phot...
متن کاملQuasi two day wave-related variability in the background dynamics and composition of the mesosphere/thermosphere and the ionosphere
Dissipating planetary waves in the mesosphere/lower thermosphere (MLT) region may cause changes in the background dynamics of that region, subsequently driving variability throughout the broader thermosphere/ionosphere system via mixing due to the induced circulation changes. We report the results of case studies examining the possibility of such coupling during the northern winter in the conte...
متن کاملObservations of stratospheric warmings and mesospheric coolings by the TIMED SABER instrument
[1] We used temperature data from the Sounding of the Atmosphere with Broadband Emission Radiometry (SABER) on the the NASA TIMED satellite to quantify the connection between temperatures in the stratosphere and in the mesosphere and lower thermosphere. Specifically, we studied three winter periods where stratospheric temperatures were dynamically disturbed: February 2002, August, 2002, and Feb...
