abstract long-term historical weather data are needed to conduct crop simulation analysis. simulated climatic data may be used when long series of historic data are not available or convenient or when future data are needed. the aim of this study was to generate daily weather values for maximum and minimum air temperatures. a number of weather generators are compared here. data from ten station...

Crop simulation models can be used to estimate impact of current and future climates on crop yields and food security, but require long-term historical daily weather data to obtain robust simulations. In many regions where crops are grown, daily weather data are not available. Alternatively, gridded weather databases (GWD) with complete terrestrial coverage are available, typically derived from...

The aim of this paper is to project extreme precipitation events in an arid and a semiarid station. In order to project climate change based on general circulation models (GCMs), we have applied LARS-WG[1] downscaling tool. This stochastic weather generator down-scaled the climate of two synoptic stations using HADCM3 model and A2 emission scenario for 2040. We extracted extreme precipitation e...

Janne Hämäläinen, M.Sc. (Eng.) Product Manager Surface Weather Division Vaisala Helsinki Finland he MILOS 520 Data Collection and Processing System is designed to satisfy the current and future requirements for Automatic Weather Stations that are accurate, reliable and economical in terms of overall costs through the entire life cycle of a system. The MILOS 520 system’s flexible set-up in a Win...

In this paper, we introduce data and information activities of the International Center for Space Weather Science and Education (ICSWSE), Kyushu University, Japan. The principal data source is the MAGDAS (MAGnetic Data Acquisition System) project which is a global network of geomagnetic observations operated by collaborations between ICSWSE and institutions in many countries. We operate 66 stat...

After the establishment of the first quarantine station in the Republic of Ragusa (modern-day Dubrovnik) in 1377, the states and principalities of Italy developed a sophisticated system of defensive quarantine in an attempt to protect themselves from the ravages of plague. Using largely unknown and unseen historical maps, this paper reconstructs the extent and operation of the system used. It i...

The paper presents results from an ongoing agricultural project where the Internet is used for efficient transfer of knowledge and technology between Denmark and the Baltic countries. Danish weather-based models for risk of crop diseases and pests have been validated under Baltic conditions and small weather stations have been installed in agricultural areas in the three countries. Web technolo...

â â â  this paper attempts to investigate the relationship between 500hpa circulation patterns and weather types (coldest, warmest and raining) over 16 synoptic stations of mountainous region of iran. the mountainous region of iran covers about 670000 square kilometer (41 percent) of iran. in this paper have been investigated the relationship between circulation patterns in 500hpa level with we...

IRELESS VANTAGE PRO2 Vantage Pro2TM (6152, 6153) and Vantage Pro2TM Plus (6162, 6163) Wireless Weather Stations include two components: the Integrated Sensor Suite (ISS) which houses and manages the external sensor array, and the console which provides the user interface, data display, and calculations. The ISS and Vantage Pro2 console communicate via an FCC-certified, license-free, spread-spec...
