[en] Complete text of publication follows. Pakistan (23-40degN, 60-80degE) is spread over 800,000 square km. The country consists of a variety of terrains with flat Indus plain to the east, mountains to the north and northwest Balochistan plateau to the west. The geomagnetic observatory at Karachi (24.95degN, 167.14degE) was established in 1983. Due to development of infrastructure and vehicular movement near the observatory, quality of the data became poor. This observatory has now been shifted to Sonmiani, 48 km north of Karachi. The site was selected after performing a magnetic survey and selecting the cleanest and lowest magnetic gradient parts. Additionally, being part of a huge government property in rural surroundings, the Sonmiani site offers long-term protection from cultural noise. The Observatory has been named after Pakistani Physicists Nobel Prize Abdus Salaam, who was Scientific Director at Sonmiani in the 1960's. Our activity: site selection, operation of Sonmiani observatory and the data from both observatories is compared and is presented. The work was carried out with collaboration of IRM, Belgium.

After the installation of geomagnetic observatory 'Abdus Salaam' in Sonmiani (South-west of Pakistan), Pakistan has established another geomagnetic observatory at Islamabad (33.75degN, 72.87degE), located in the North-east mountainous region of the country. Since Pakistan is spread along 23-40degN, 60-80degE, the newly established observatory will provide enhanced coverage of geomagnetic activity in the country. During 2008, repeat station work at three selected sites (Multan, Gilgit and Skardu) was also carried out to compare with the survey work previously done during 2005. All this activity was the result of collaboration between SUPARCO and IRM started in 2006 and which culminated in July 2008 by this joint installation and measurement campaign. Experiences during establishment of the observatory and repeat station comparisons/results are described in this study.
[en] Complete text of publication follows. The INDIGO project aims to improve the global coverage of digital observatories by deploying digital magnetometer systems in: i) Observatories where existing analog recording equipment is in need of upgrading. ii) Newly established digital observatories. iii) Existing digital observatories for the purpose of quality control and redundancy. In implementing the project and selecting suitable sites, special attention is paid to parts of the Earth devoid of magnetic observatories, increasing the reliability and long-term operation of existing observatories and cost-effective use of local resources. The Poster reviews the current status of the project. We examine the different steps and initiatives taken since the initiation of INDIGO in 2004 and assess their effectiveness in achieving progress towards our aims of improving global coverage and enhanced data quality.
