IAGA Publications, Products and Standards IAGA News | IAGA Flyer & Poster | IAGA Guides | IGRF | Data Formats The newletter "IAGA News" contains items and announcements of general interest to the IAGA community. IAGA News is sent free of charge to all addresses on the IAGA mailing list and is available on request from the Secretary-General, who also maintains information on availability and price of other IAGA publications.
IAGA has two publications summarising and illustrating its scientific interests and activities:
IAGA Guides document methods and standards of observation of geophysical phenomena. 1. Observing Noctilucent Clouds
This manual and instruction book was written by a group of active researchers, both professional and amateur. There are chapters giving practical advice for taking visual observations, photographing the clouds with film or with video equipment. A summary of observations from space is included, as well as comments on the connection between noctilucent clouds, seen from the ground, and the polar mesospheric clouds that so far have been measured only from orbit. Noctilucent clouds are seen in the summer months, shining in the poleward sky at nighttime. Measurements show that the clouds are higher than any others. Lying at a height of 80-85 kilometers, the clouds mark a boundary between meteorology and space physics. This book is beautifully illustrated with photographs, and will help everyone recognize and appreciate these "sailors in the summer night". Stocks of the original book are now exhausted, but an electronic version is available (as of September 2006) in pdf format and may be downloaded free of charge using the following link: Observing Noctilucent Clouds (pdf, 1 Mb) The photographs in the book may be viewed at Pekka Parviainen's web site: www.polarimage.fi (A cross-referenced index to the photographs is given in Appendix A of the pdfdocument.)
This Guide provides comprehensive information about how to organize and run a magnetic observatory and make magnetic measurements. The main topics are:
This Guide provides a comprehensive description of the theoretical basis, operational details, and instrumentation for making magnetic repeat station survey measurements.
