Ozonesonde
Network
The pre-deployment phase of TRACE-P, consisting
of a 12 ozonesonde network, was initiated to provide a time history
of tropospheric ozone in the TRACE-P study region and to augment
the data obtained aboard the aircraft during deployment. Ozonesonde
balloons are released from Trinidad Head, California; Hilo, Hawaii;
Sapporo, Tateno Naha, and Kagoshima Japan; Watukosek, Indonesia;
Suva, Fiji; Pago Pago, American Samoa; Hong Kong; Taiwan; and
Cheju Island, Korea (Figure 2.5-1).
The sondes from Trinidad Head, California and
Hilo Hawaii are included in TRACE-P as sites operated by PI Sam
Oltmans (see section 4.5.2). The
Cheju Island, Korea site is
operated by Jae Kim, a co-investigator of Sam
Oltmans. The Sapporo, Tateno, Naha, and Kagoshima,
Japan sites are included as part of an agreement with the Japan
Meteorological Agency and Hideyuki Sasaki. These
are standard on-going releases, which have a data sharing agreement
with TRACE-P (see Section 2.4.4 and Appendix M). The
ozonesondes at Indonesia;
Fiji; and American Samoa are maintained by SHADOZ (Southern Hemisphere
ADditional OZonesondes) and provided to TRACE-P through PI Anne
Thompson. The ozonesonde data at Hong Kong and Taiwan
are provided to TRACE-P per agreements described in Sections
2.4.2 and 2.4.6, respectively. Data
sharing will conform to the TRACE-P Data Protocol
(see Section 6.1).

responsible for ozonesonde operations at each site as well as

Data Archival:
Typical ozonesonde data received at Langley
are: time, pressure, geopotential height, temperature, relative
humidity, ozone partial pressure, etc. All levels received are reprocessed into GTE
format. Basic QC are
performed and bad data are removed. If ozone mixing ratio is
not provided, then, it is calculated for input into the GTE format.
At Langley, the work is straight forward: receiving
the data, performing low level QC (reporting PI's are responsible
for quality), calculation of missing values, if possible, and
putting data into a common GTE format, and archiving the data
for use by PI's.
