The station has been installed and commissioned on the roof of the exams hall building at the National University of Science and Technology (NUST) campus in Islamabad, Pakistan (33.642°N, 72.984°E). The station is fully operational and taking the measurement values listed in the sec- tion below. It is equipped with a Solys2 Tracker with a CHP1 pyrheliometer and two ventilated CMP21 pyranometers for global and diffuse irradiation measurement (all manufactured by Kipp&Zonen), a Campbell Scientific CR1000 data logger, tempera- ture and relative humidity sensor and barometric pressure sensor. A wind tower is installed at the station. The wind speed and wind direction sensors (manufactured by NRG) are on a total height of 8 m above the roof top (due to re- duced available area on the rooftop and resulting difficulties with guy wire lengths). All sensors are integrated into the Tier1 meteorological data acquisition system. Power supply is provided by NUST. It consists of a 230 VAC surge-protected power grid connection. The measurement system includes a UPS and batteries for continu- ing operation of at least 24 h in case of main power failure. Station maintenance will be done by local staff of NUST. The local personnel have been briefed on how the maintenance has to be done. The main task is to clean all three irradiance sensors on a daily basis. Upon request, further tasks as checking the levelling of the sensors, stability of the equipment, etc. might be carried out. Regular inspection and maintenance visits will be performed on a six-monthly inter- val by the company PITCO, local partner of the ESMAP solar vendor consortium. Calibration certificates for the installed sensors will be handed over to Alternative Energy Development Board of Pakistan (AEDB) and World Bank (WB) together with the station documentation and manual. Data retrieval will be done by CSPS via GPRS data transmission on a daily schedule, starting with the first day after installation; data will be provided to AEDB, WB and approved stakeholders on a daily basis by email in Excel format as well as on a data publication platform provided by WB.
