7、034-1998) ii Approval of an American National Standard requires verification by ANSI that the requirements for due process, consensus, and other criteria have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreem

8、ent has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. The use of Ame

The proliferation of ionos

25、pheric models and the lack of documentation have hindered general knowledge of their availability as well as their relative strengths, weaknesses, and limitations. The intent of this guide is to compile, in one reference, practical information about known and available ionospheric modelsthose that d

26、escribe the physical properties and practical effects of the ionosphere as a function of altitude, latitude, and other key parameters. At this writing, the included models are those intended for general purpose, scientific, or aerospace applications and therefore extend to heights ranging from 50 to

27、 10,000 km. Dynamical models of the ionosphere are included in this guide, as the dynamics are essential to many applications. The guide summarizes the principal features of the models: Model content Model uncertainties and limitations Basis of the model Database or model input parameters Publicatio

28、n references Dates of development, authors, and sponsors Model codes and sources. The models are grouped according to whether they describe primarily global, regional, or special properties. There is limited information on standard deviations from the mean values or frequencies of occurrence of some

29、 of the variables described by these models. This limits quantitative assessments of uncertainties. Correlation distances for electron densities, and statistics on scintillation are well defined. These and other statistics are discussed in the body of the guide. Candidates for inclusion in this guid

30、e have been solicited by means of advertisements in publications including announcements at national and international meetings of URSI, IAGA, AGU, COSPAR, AIAA, and scientific community newsletters. This collection of models is not exhaustive. It is hoped that future editions will include additiona

31、l models from the international community. We are indebted to those authors who submitted their models for inclusion, to those who offered valuable advice, to Jared Fulgham for notable assistance, and to the editors/reviewers: W. Kent Tobiska (Editor), Robert W. Schunk, Herbert C. Carlson, and Ludge

The second revision was initiated in 2010 and approved in March 2014 by the AIAA Atmospheric and Space Environments Committee on Standards (ASE CoS).

38、, Andrew Shapiro, and John Wise. This 2014 revision of Guide to Reference and Standard Ionosphere Models contains updated information on several models relative to information on references, sources, and so forth. In addition, a few of the models in the previous edition that are now obsolete have be

39、en replaced with updated versions. The model for which updated information is provided is the NCAR Thermosphere-Ionosphere-Electrodynamics General Circulation Model (TIE-GCM). Some new models that have been added include the following: 1. The Assimilative Mapping of Ionospheric Electrodynamics (AMIE

43、 Every attempt has been made to obtain information from modelers in the community. However, ASETC CoS is aware that new models may have recently been developed and older models exist but may not have been incorporated into this document. We appreciate any information that could lead to reporting of

44、models that are not included here. The AIAA Atmospheric and Space Environments Committee on Standards (W. Kent Tobiska, Chairperson) approved this document for publication in March 2014.
