Climatology 2011: An MLS and Sonde Derived Ozone Climatology for Satellite Retrieval Algorithms The ozone climatology used as the a priori for the version 8 Solar Backscatter Ultraviolet (SBUV) retrieval algorithms has been updated. The Microwave Limb Sounder (MLS) instrument on Aura has excellent latitude coverage and measures ozone daily from the upper troposphere to the lower mesosphere.

Abstract Pump efficiency of the Brewer–Mast (B–M) ozone sonde deteriorates significantly at altitudes above 22 km (pressures below 50 hPa). The correction currently used as the WMO standard does no...
TES sonde differences are examined in six latitude zones after excluding profiles with thick high clouds. Values for the bias and standard deviation are determined using correlations of mean values of TES ozone and sonde ozone in the upper troposphere (UT) and lower troposphere (LT). The UT biases range from to ppbv,

An ozone sonde capable of measuring and transmitting the local ozone concentration has been developed for the I. G. Y. and is described in some detail. A continuous electrochemical detector measures the ozone concentration, providing a d. c. electric current of 0 to 5 μA according to the amount of ozone in the air passed through it. This ...

Feb 01, 1998· Relative ozone difference between B–M and ECC sondes during the WMO ozone sonde intercomparison in Vanskoy, Canada, 1991, after Kerr et al. (1994), and between HALOE (version 17 data) and B–M sondes at Hohenpeissenberg, after Brühl et al. (1996). The B–M sonde data were processed using the WMO standard pump correction.
The Dobson Unit (DU) is a unit of measurement of ozone found in a column of air stretching from the surface of Earth to the edge of the atmosphere. It is given as the thickness of the layer formed by ozone molecules in a column under standard temperature and pressure. For example, 300 DU of ozone brought down to the surface of Earth at 0°C ...
Ozone sounding records constitute the longest time series of the vertical ozone distribution between the surface and 3035 km altitude. Vertical ozonesonde profiles provide the single data source with sufficient vertical resolution to resolve the vertical ozone gradients, particularly at the tropopause region. Ozonesondes also constitute a backbone for keeping ozone measuring satellites ...
Apr 04, 2020· SHADOZ (Southern Hemisphere ADditional OZonesondes) is designed to remedy this data discrepancy, by coordinating launches, supplying additional sondes in some cases, and by providing a central archive location. Since 1998, ozonesonde data have been collected and made available through this website. Q uestions regarding sonde data from specific ...
Ozonesonde. The ozonesonde is a lightweight, balloonborne instrument that is mated to a conventional meteorological radiosonde. As the balloon carrying the instrument package ascends through the atmosphere, the ozonesonde telemeters to a ground …
OWLETS2_Sondes_Data_1 is the Ozone WaterLand Environmental Transition Study (OWLETS1) ozone data collected via synchronous ozonesonde launches at the Howard University Beltsville (HUBV) and University of Maryland Baltimore County overland sites and Hart Miller Island overwater site during the OWLETS2 field campaign.
Apr 04, 2018· How it Works. Unlike some ozonesondes, ECC sondes do not require an external electrical potential. The ECC gets its driving electromotive force from the difference in the concentration of the potassium iodide solutions in the instrument’s cathode and anode chambers. When ozone enters the sensor, iodine is formed in the cathode half cell.
To increase the ozone sonde autonomy, a strategy has been adopted of short measurement sequences (typically 23 min) regularly spaced in time ( every 15 min, which is usually sufficient for air quality studies). The rest of the time, the sonde is at rest (pump motor off).
Oct 21, 2019· 2019 Ozone Hole is the Smallest on Record Since Its Discovery. Abnormal weather patterns in the upper atmosphere over Antarctica dramatically limited ozone depletion in September and October, resulting in the smallest ozone hole observed since 1982, NASA and NOAA scientists reported today.

The OzoneSonde is a lightweight, balloonborne instrument that is mated to a conventional meteorological radiosonde. As the balloon carrying the instrument package ascends through the atmosphere, the OzoneSonde telemeters to a ground receiving station information on ozone and standard meteorological
ozone. In the tropics, sonde station coverage is now much better because of the augmented sonde data from the SHADOZ (Southern Hemisphere Additional Ozonesondes) network [Thompson et al., 2003]. In the zone from the equator to 10 S there are now 5 sonde sites that give fairly good sampling with longitude. Finally, notice that in the
Weekly balloonborne ozone profiles are measured at the South Pole Observatory (station code SPO) on the Antarctic continent: ° South, ° West: 2810 meters above sea level. Date of Measurements: 1986 – current. You can view vertical profiles of ozone sondes from South Pole. Data files for the Summit ozonesondes can be found at.

Aug 09, 2021· Ozone is a colorless gas. Chemically, ozone is very active; it reacts readily with a great many other substances. Near the Earth’s surface, those reactions cause rubber to crack, hurt plant life, and damage people’s lung tissues. But ozone also absorbs harmful components of sunlight, known as “ultraviolet B”, or “UVB”.
