      The meteorological stations use MicroMet AQ. This software is capable of performing calculations for air quality applications and it has the capability of monitoring and calibrating various types of analyzers. Also, using this program, the monthly database of all collected data can be archived or backed up to prevent loss of data. The MicroMet AQ stores all data in a monthly database that only grows in size to accommodate a month of data for each of the 12 months.

      Through the EXPORT function, data can be exported directly into an Excel spread sheet, of hourly values each month, or into a CSV (comma separated values) file of any collected data. This file format is set by the operator, so that it can be configured to be compatible with other users, or software that may be using the collected meteorological data. Every time data is collected from the remote station, the data collected can be output into a text file that can be used by other programs operating on the host computer. This special function can be utilized to provide data to another graphics program which can be used to map the data and generate contour plots. This output can also been used to provide data to a Web Page that is providing current weather data from each remote location. At present, some researchers at KISR are working on publishing the meteorological information on KISR’s website.

      Using MicroMet AQ, the eight MetOne meteorological stations are networked allowing a central PC at KISR’s headquarter in Shuwaikh to automatically poll the data at a pre-specified times each day using GSM communication protocols. Every morning, weather charts are plotted and carefully examined to decide on daily maintenance activities.

      The harsh conditions surrounding the meteorological sensors meant that a continuous maintenance activity was required to keep them operational. Regular maintenance activities include:
    > replacing bearings of wind speed sensors (bearing are replaced every three months during the winter season and every two months during the summer season).
    > cleaning the evaporation pan from algae and sand and replacing the water inside it.
    > cleaning the read switches in the rain gauges and the tipping bucket mechanisms.
    > replacing faulty level switches in water tanks and evaporation pans.
    > refilling the underground water tanks (once during the winter season and once every three months during the summer season).
    > resetting the modem and the data logger (whenever communication with the station is lost due to power failure or signal carrier fault).
    > calibrating the wind speed and direction sensors (halfway between routine bearing replacement).
    > cleaning and calibrating the relative humidity sensors (once every three months).
    > removing the encroaching sand from the station’s perimeter to reduce the risk of sensor burial with sand.
    > cleaning the solar radiation sensor and the solar panel and.
    > checking the submerged pump filling rate and replacing it when necessary.

Most of the sensors repair and calibration is done either at the Center, where we have a well equipped mini repair workshop, or onsite.
