Launch of an Ozone Sonde in Uccle – Sondehunt

Aug 01, 2019· ECC ozone sondes are used, since the middle of the 90s, before Brewer-Mast sondes were used. In general a normal radiosonde, here a Vaisala RS41, is used for ozone sounding. The ozone measuring device is connected to this sonde, which consists of an electrochemical reaction cell, a sampling pump, a control board and the necessary batteries, and ...

NASA Ozone Watch: Latest status of ozone

Jul 27, 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 “UV-B”.

Sondes - an overview | ScienceDirect Topics

The KC96 ozone sonde type is a modified version of the KC79- and the earlier KC68-sonde, which was developed by Kobayashi and Toyama in 1966. These sonde types are based on the carbon–iodine ozone sensor type developed in the early 1960s. The ozone sensor is a single electrochemical cell containing a platinum gauze as cathode and an activated ...

ECC Ozonesonde - EN-SCI

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.

Ozone Sonde Data Quality Assessment: New Insights from the ...

Ozone sounding records constitute the longest time series of the vertical ozone distribution between the surface and 30-35 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 ...

ESRL Global Monitoring Laboratory - Ozone and Water Vapor

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 ...
