Büyükbas (Turkey) L. Yalcin (Turkey) Z.T. Dag (Turkey) S. Karatas (Turkey) WMO/TD-No. 1307 2006 NOTE The designations employed and the presentation of material in this publication do not imply the expression of any opinion whatsoever on the part of the Secretariat of the World Meteorological Organization concerning the legal status of any country, territory, city or area, or its authorities, or concerning the limitation of the frontiers or boundaries. This report has been produced without editorial revision by the Secretariat. It is not an official WMO publication and its distribution in this form does not imply endorsement by the Organization of the ideas expressed. FOREWORD The Thirteenth Session of the Commission for Instruments and Methods of Observation (CIMO) recognized the need for training and placed a greater emphasis on these issues as it planned its activities for its 13th Intersessional period. As next generation automated weather observing systems are deployed the need for more in depth training in instrument and platform siting, operation, calibration, and maintenance has been requested. Within this document the team of experts from Turkey, led by Mr Büyükbas, provided training materials that address the basic training needs requested by Commission Members. This excellent work will undoubtedly become a useful tool in training staff in many aspects of automatic weather observation systems. I wish to express our sincere gratitude to Mr Büyükbas and his colleagues in preparing such a fine series of documents. (Dr. R.P.

OBJECTIVES OF THE COURSE This course has been planned to be organized within the scope of the tasks of Expert Team on Training Activities and Training Materials established by CIMO Management Group (OPAG on Capacity Building (OPAG-CB)/C.1. Expert Team on Training Activities and Training Materials) This course is expected to give a general view and information to the trainees about the basic features of Automated Weather Observing System (AWOS) and why and how to operate an AWOS network. It is believed that to organize such training courses will give an invaluable contribution to the capacity building activities and will be a great opportunity to be able exchange the experiences and information between the meteorological services of different countries. On the other hand, as in that case, Regional Meteorological Training Centres will be used more efficiently. Turkish State Meteorological Service (TSMS) started modernization program of observation network and got many experience both on equipment itself and operating them. So TSMS’s well trained staff will take the opportunity to transfer their knowledge and experiences to the representatives of the other countries and get their experiences, comments and recommendations by means of that interactive training course. Upon completion of the course; Trainees will be able to; a) understand why we need more reliable, more accurate and continuous meteorological data and how these requirements can be met, b) learn basic principles and approach of an AWOS which has become a necessity for the meteorological observations, c) take the opportunity to inspect an operational AWOS and to make practical applications on it, d) get the view how to maintain a single AWOS and an AWOS network. Trainers will be able to; a) understand weak and strong parts of their knowledge and teaching method, b) learn how they can transfer their knowledge to the trainees, c) take the opportunity to check their system’s features once more under the inspection and questions of the trainees, d) get comments, experiences and recommendations of the representatives of the other countries. http://rmtc.meteor.gov.tr 1 Training Course on “AUTOMATED WEATHER OBSERVING SYSTEMS” 06-10 June 2005 2.

Submitted photo courtesy of WKU Visitors to Ephram White Park might notice a new feature – a Kentucky Mesonet weather station has been relocated to the park from its previous location near the General Motors Corvette plant. Stuart Foster, director of the Kentucky Mesonet and the Kentucky Climate Center, said the move comes after the station was damaged during a lightning strike. He said the new location shouldn’t afect forecasting in the area. On the contrary, the real- time weather information the station ofers could become even more valuable in its new location at the park at 885 Mount Olivet Road. “With the growing population, nearby schools and industrial park, we felt it was important to keep coverage in that area so we worked with Chris Kummer and Warren County Parks and Recreation and partnered with them on the site at Ephram White Park,” Foster said in a news release. Part of a statewide network of 71 stations in 69 counties, the Mesonet station collects real- time data on temperature, precipitation, humidity, barometric pressure, solar radiation, soil moisture, soil temperature, wind speed and direction. That data is transmitted to the Kentucky Climate Center at WKU every fve minutes, 24 hours a day throughout the year, and is available online at kymesonet.org.

BREAKER National Weather Service, NCEP, NOAA, Washington, D.C. DAVID B. GILHOUSEN National Weather Service, National Data Buoy Center, NOAA, Stennis Space Center, Mississippi LAWRENCE D. BURROUGHS National Weather Service, NCEP, NOAA, Washington, D.C. (Manuscript received 1 April 1997, in ®nal form 18 July 1997) ABSTRACT Measurements of boundary layer moisture have been acquired from Rotronic MP-100 sensors deployed on two National Data Buoy Center (NDBC) buoys in the northern Gulf of Mexico from June through November 1993. For one sensor that was retrieved approximately 8 months after deployment and a second sensor that was retrieved about 14 months after deployment, the pre- and postcalibrations agreed closely and fell within WMO speci®cations for accuracy. A second Rotronic sensor on one of the buoys provided the basis for a detailed comparison of the instruments and showed close agreement. A separate comparison of the Rotronic instrument with an HO-83 hygrometer at NDBC showed generally close agreement over a 1-month period, which included a number of fog events. The buoy observations of relative humidity and supporting data from the buoys were used to calculate speci®c humidity. Speci®c humidities from the buoys were compared with speci®c humidities computed from observations obtained from nearby ship reports, and the correlations were generally high (0.7± 0.9). Uncertainties in the calculated values of speci®c humidity were also estimated and ranged between 0.27% and 2.1% of the mean value, depending on the method used to estimate this quantity.
