Characteristics and error estimation of stratospheric ozone and ozone - related species over Poker Flat ( 65 ◦ N , 147 ◦ W ) , Alaska observed by a ground - based FTIR spectrometer from 2001 to 2003
It is important to obtain the year-to-year trend of stratospheric minor species in the context of global changes. An important example is the trend in global ozone depletion. The purpose of this paper is to report the accuracy and precision of measurements of stratospheric chemical species that are made at our Poker Flat site in Alaska (65 • N, 147 • W). Since 1999, minor atmospheric molecules ...
متن کاملMF radar observations of mean winds and tides over Poker Flat , Alaska ( 65 . 1 ◦ N , 147 . 5 ◦ W )
MF radar wind measurements in the mesosphere and lower thermosphere over Poker Flat, Alaska (65.1 N, 147.5 W) are used to study the features of mean winds and solar tides. Continuous observation with the newly installed radar is in progress and in the present study we have analyzed a database of the first 27 months (October 1998–December 2000) of observation. The observed mean wind climatology ...
متن کاملQuasi-Lagrangian Measurements of Nitric Acid Trihydrate Formation Over Antarctica
In 2010, the joint French-United States Concordiasi project released 19 long-duration superpressure balloons from McMurdo Station, Antarctica. Four of these balloons carried a gondola with particle counters and temperature sensors to measure polar stratospheric clouds. One gondola spent 5 days at stable temperatures between equilibrium temperatures for nitric acid trihydrate (NAT) and for super...
متن کاملEvolution of stratospheric temperature in the 20th century
[1] We employ a coupled atmosphere-ocean climate model to investigate the evolution of stratospheric temperatures over the twentieth century, forced by the known anthropogenic and natural forcing agents. In the global, annual-mean lower-to-middle stratosphere ( 20–30 km.), simulations produce a sustained, significant cooling by 1920, earlier than in any lower atmospheric region, largely resulti...
متن کاملA tropical West Pacific OH minimum and implications for stratospheric composition
Most of the short-lived biogenic and anthropogenic chemical species that are emitted into the atmosphere break down efficiently by reaction with OH and do not reach the stratosphere. Here we show the existence of a pronounced minimum in the tropospheric column of ozone over the West Pacific, the main source region for stratospheric air, and suggest a corresponding minimum of the tropospheric co...
