*************************** ** THE GEM MESSENGER ** *************************** Volume 15, Number 3 January 18, 2005 -------------------------------------------------------------------------- AMIE Maps, Code, and Tools -------------------------------------------------------------------------- From: Aaron Ridley We have recently completed 12 years of runs of the Assimilative Mapping of Ionospheric Electrodynamics (AMIE) technique (1991-2002). These runs were made using between 40 (~1991) and 150 (~1999+) ground-based magnetometers. AMIE produces maps of ionospheric potential, electric fields, particle precipitation, conductance, and Joule heating. We have run on a 1 minute time cadence, so there are approximately 6 million maps of each of these quantities. In addition, summary plots are created to give the cross polar cap potential, AE, Dst, hemispheric power index, Joule heating, and number of magnetometers used in the inversion. At this time, plots are created dynamically as you select the interval and variable to plot. The raw data files can be provided by e-mailing me. We can supply the data files and plotting tools in IDL to visualize them. In addition, we can supply FORTRAN 90 codes to read the data sets in geographic or magnetic coordinates for use in other models (like ionospheric or magnetospheric models). The AMIE visualization tool can be found at http://amie.engin.umich.edu/ We more than welcome any community feedback on the interface, the accuracy of the inversions, or any other aspects of the AMIE University of Michigan site. +-------------------------------------------------------------------------+ |To subscribe GEM Messengers, send an e-mail to | | with the following command in the body of your e-mail message: | | subscribe gem | |To remove yourself from the mailing list, the command is: | | unsubscribe gem | | | |To broadcast a message to the GEM community, please contact Peter Chi at | | | |Please use plain text as the format of your submission. | | | |URL of GEM Home Page: http://www-ssc.igpp.ucla.edu/gem/Welcome.html | |Workshop Information: http://gem.rice.edu/~gem | +-------------------------------------------------------------------------+
