Abstract:
Observations of meteorological and sea-ice variables were carried out at Chaivo,
northern Sakhalin during the period from October 2002 to November 2003, as part of the
Japan-Russia cooperative research project "Sea Ice Studies off the Okhotsk Sea Coast of
Sakhalin". Time series data of wind, air and surface temperatures, humidity, solar radiation and
atmospheric pressure were summarized in this report.

I. Introduction
As part of the Japan-Russia cooperative research project, "Sea Ice Studies off the Okhotsk
Sea Coast of Sakhalin", observations of meteorological and sea-ice variables were carried out at
Chaivo, northern Sakhalin (Fig. 1) during the period from October 2002 to November 2003 to
characterize atmospheric variables and sea-ice formation in northern Sakhalin throughout all the
year round. Time series of air and surface radiative temperatures, humidity, wind speed and
direction, radiation and atmospheric pressure obtained at an automatic weather station of the
Chaivo Research Station (Fig. 2), located near the shore of Kleye Strait are shown in this report.
Prior to this study, field experiments of meteorological and sea-ice studies had been carried out
at the Chaivo Research Station since 1992, as part of the Japan-Russia cooperative research
project, "Sea Ice Studies off the Okhotsk Sea Coast of Sakhalin". Some of the meteorological
variables and sea-ice characteristics obtained from this project were reported in Shirasawa et al.
(1994, 1996, 1998,2000,2001 and 2002).
II. Meteorological variables at Chaivo Research Station
The Chaivo Research Station (52°21.50'N, 143°11.93'E) is located near the shore of
Kleye Strait, which links Chaivo Bay to the Sea of Okhotsk (Fig. 1). The Chaivo Research
Station has been operated all the year round by the JSC Sakhalin Projects (former Sakhalin Oil
and Gas Institute). An automatic weather station (Data Logger SQ-1201, Grant Instruments
Ltd.) was installed on the roof of Chaivo Research Station about 6 m high from the ground in
order to obtain general meteorological variables such as air temperature, humidity, wind speed
and direction, radiation and atmospheric pressure through all the year round (Fig. 2). Two
radiative temperature sensors (Tasco Co., Ltd.) were also installed at the edge of the shore near
the station (Fig. 2). One sensor being faced to the sea surface to measure the surface
temperature, the other was faced to the sky to measure the diffuse sky temperature.
Time series records of air temperature at 1 m, humidity at 1 m, wind speed and
direction at 2.1 m and radiation at 0.85 m height from the roof of Chaivo Research Station (at 6
m high from the ground) are shown in Fig. 3. An atmospheric pressure sensor was installed in
the cabin of the station. The maximum air temperature was observed at about 24°C on 20
August 2003, and the minimum temperatures were about -30°C on 10 December 2002 and 12
January 2003. The relatively stronger winds over 15 mls were observed on 14 October, 13
November and 5-6 December 2002, and 29 January, 11 February and 25 March 2003. Wind
roses for each month from October 2002 through November 2003 shown in Fig. 4 indicate
predominantly northwesterly winds during the period from December through March.

In this report the time is used in the Japanese Standard Time (JST). The wind
direction is used in reference to the magnetic north, which is deviated 14° from the true north.
The threshold value of wind speed is used as 0.3 mls.
Acknowledgements
We wish to thank all staff at the Chaivo Research Station for their assistance and effort in
the field and laboratory. Funding for this work was partly obtained from the Japanese Ministry
of Education, Culture, Sports, Science and Technology (MEXT) through the Sea Ice Research
Laboratory's Overseas Field Work Program.
