IGPP/LANL
An Introduction
Presented at 1998 Spring AGU Meeting
The IGPP/LANL Magnetometer Array is a collaborative effort among the two Universiity of California campuses (Berkeley and Los Angeles), the Los Alamos National
Laboratory, and the US Air Force Academy. In this effort, we are installing an array of mid-latitude ground magnetometer stations in the US, as shown in Figure 1. The
primary funding for the first four stations of IGPP/LANL has been awarded by Los Alamos branch of Institute of Geophysics and Planetary Physics. The funding to complete
the array is still pending.
In the IGPP/LANL Array shown in Figure 1, we will re-instate the AFGL magnetometer network which operated in 1977-1978. The AFGL network consisted of five
northern US Air Force base sites and two southern sites. We will extend its southern chain with totally five sites. In addition, one more station will be deployed at Colorado
Springs, CO (the Air Force Academy site) and Boulder, CO, in order to familiarize the Air Force students with the installation procedure and normal operations of the
magnetometer and another one at Los Alamos (LANL), in order to ensure that pulsation studies and their correlations with LANL spacecraft data can be done internally at
LANL. Figure 2 show pictures of LANL Fenton Hill site. In the map in Figure 1, we also show the locations of UCLA test site in San Gabriel
Dam, and correlative site in Mexico City. When the full deployment is completed the chain will have a 55 and a 40 corrected geomagnetic longitude chain with very good
longitudinal resolution for timing of SI propagation, current wedge modeling, and Pi 2 and Pc 3-4 propagation.
Including the associated sites, five sites are now operational: San Gabriel Dam test site, Mexico City site, Jicamarca site, the LANL Fenton Hill site, and the Air Force
Academy site. The later two sites can accommodate a fast real time internet connection for rapid dissemination of data. It is our goal to have internet access to all these
sites in the near future. The magnetometers for the next two IGPP/LANL sites (Rapid City, SD, and San Antonio, TX)
have been assembled at UCLA lab and are being
tested at UCLA San Gabriel Dam test site.
