The presence of SO 2 interferes with the standard electrochemical cell (ECC) ozonesonde measurement, resulting in –1 molecule of O 3 reported for each molecule of SO 2 present (provided [O 3].[SO 2]). In laboratory tests.
ozonesonde batch. • Some of our Z12xxx sondes were used in the most recent JOSIE intercomparison campaign and did not lead to any observed discrepancies in these vacuum chamber tests (H. Smit, private communication). • When we calculate the monthly means for the total amount of ozone in the km layer from the sounding’s. Intercomparison of Ozone and Temperature Profiles During OZITOS+ Campaign in Río Gallegos, Argentina: Authors: (DIAL), ozonesonde and Millimeter Wave Radiometer (MWR). Also other ground-based and satellite-based instruments were included in the experiment but in this work we only present preliminary results from ground-based.
The intercomparison results show a consistent picture. By not exposing the ozonesonde to ozone during preparation, and by assuming a constant background current measured in the laboratory immediately before launch, ozonesonde profiles were measured and agreed with the GV to 3 ppbv between and hPa (Newton et al. ).

technique, instrument type, sensor solution, and data processing, demonstrating the need to homogenize available ozonesonde data sets and standardize future operational procedures for reliable and consistent satellite validation. As a consequence, there are biases among different stations and discontinuities in profile time series from individual site records.
For 22 years the Jülich (Germany) Ozonesonde Intercomparison Experiment (JOSIE) has periodically tested ozonesondes in a simulation chamber designated the World Calibration Centre for Ozonesondes (WCCOS) by by: 2.
An Indo-Soviet collaborative experiment on Ozonesonde Intercomparison was conducted at TERLS in March Thirteen rocket ozonesondes, eleven balloo Cited by: 7. The magnitude of variations and errors in ozonesonde measurements in the middle stratosphere have been fairly consistent in showing larger variability in this region from past intercomparison projects and individual tests, thus indicating that trend analysis may be less reliable at these altitudes.

Central processing issue: There are 6 radiosonde/ozonesonde. Experimental diagram for the electrochemical concentration cell (ECC) ozonesonde pH sensitivity tests. The ozonesonde sampled a constant ozone source while the pH of the cathode sensor solution was monitored continuously.
The pH of unbuffered sensor solutions could be adjusted between and by connecting or removing the carbon dioxide by: Ozonesonde preconditioning test units and the ECC instruments were provided by FZJ from a pool of loaned supplies.
Participants were split into two groups (Table 3), each of four teams operating ozonesondes of the type used in SHADOZ (Table 2).Cited by: 2.
Japanese Ozonesonde: KC and RSII-KC This ozonesonde type is based on a modified version of the carbon-iodine ozone sensor (Komhyr, ). The ozone sensor is an electrochemical cell containing a platinum gauze as cathode and an activated carbon anode immersed in an aqueous neutral potassium iodide/potassium bromide solution.
In general, a test programme is designed to ensure that an instrument or measuring system will meet its specified performance, maintenance and mean-time-between-failure requirements under all expected operating, storage and transportation conditions.
mcpeters et al.: stratospheric ozone profile intercompari similar laboratory tests with an ECC ozonesonde and reported up to 7% higher measured ozone after 90 min. To carry out the tests according to the Standards and test procedures defined.

A GSFC Super Loki optical ozonesonde instrument was flown as part of the ozone sensor intercomparison balloon campaign at Gap, France, in June A primary objective was to confirm biases between external absorption techniques, such as the GSFC sonde, and in situ techniques, which include ECC, Mast-Brewer, and DASIBI by: 6.
Abstract. On the basis of extensive laboratory and field tests of electrochemical concentration cell (ECC) ozonesondes, a height-dependent artifact in ozone profile measurements was found that is primarily due to side reactions of the phosphate buffers used in the "standard" 1% potassium iodide sensing by: A more complete documentation of the entire set of numerical experiments is given in Part 2 of the Sea Wave Modeling Project (SWAMP group, ).
The main purpose of the intercomparison study was to test our present understanding of the physics of. wind-generated surface waves from the viewpoint of.  To achieve consistent data sets quality assurance (QA) of ozonesonde performance is a pre‐requisite.
QA is achieved by intercalibration and intercomparison of existing ozonesonde types as well as through standardization of procedures for preparing and data processing of ozonesondes [WMO/GAW report No. ].Cited by: Ozonesonde 57 of 92. The ozonesonde will be launched following the instructions in the chosen proposal.
Once the data is collected it will be available to you on the shared drive. Your group should produce a plot of the ozone profile from the ozonesonde and then follow the instructions in the assessment section on how to complete your Size: 1MB. EN-SCI ECC Ozonesonde This lightweight, compact and inexpensive balloon-borne instrument is the tool used around the world for measuring atmospheric ozone.
