+		International Reference Ionosphere 2012 (IRI2012) Software
+		----------------------------------------------------------
+
+================================================================================
+
+The IRI is a joined project of the Committee on Space Research (COSPAR) and the 
+International Union of Radio Science (URSI). IRI is an empirical model specifying
+monthly averages of electron density, ion composition, electron temperature, and 
+ion temperature in the altitude range from 50 km to 1500 km.
+
+This directory includes the FORTRAN program, coefficients, and indices files for 
+the latest version of the International Reference Ionosphere model: IRI2007. This
+version includes several options for different parts and parameters. A logical
+array JF(30) is used to set these options. The IRI-recommended set of options
+can be found in the COMMENT section at the beginning of IRISUB.FOR. IRITEST.FOR 
+sets these options as the default.
+
+The compilation/link command in Fortran 77 is:
+f77 -o iri iritest.for irisub.for irifun.for iritec.for iridreg.for igrf.for 
+ cira.for iriflip.for
+
+================================================================================
+IMPORTANT: Please note that the following files have NOT been changed and are the
+same as for IRI2007: CCIR%%, URSI%%

+ 
+Directory Contents:
+-----------------------------------------------------------------------------------
+
+00_iri2012.tar	TAR file that includes all files from this directory. Was created
+                in UNIX using 'tar -cvf 00_iri2007.tar *'. UNIX command to unpack
+                is "tar -xvf 00_iri2007.tar". 
+				 
+irisub.for      This file contains the main subroutine iri_sub. It computes 
+                height profiles if IRI output parameters (Ne, Te, Ti, Ni, vi) 
+                for specified date and location. Also included is the 
+                subroutine iri_web that computes output parameters versus
+                latitude, longitude (geog. or geom.), year, day of year, hour 
+                (LT or UT), and month. An example of how to call and use iri_web 
+                is shown in iritest.for. Compilation of iritest.for requires
+                irisub.for, irifun.for, iritec.for, iridreg.for, igrf.for, and
+                cira.for.
+
+irifun.for      This file contains the subroutines and functions that are 
+                required for running IRI.
+
+
+iriflip.for     Subroutines for the FLIP-related new model for the bottomside
+                ion composition of Richards et al.
+                
+iridreg.for     Subroutines for the D region models of Friedrich-Torkar
+                and of Danilov et al.
+
+iritec.for      This file includes the subroutines for computing the ionospheric 
+                electron content from 60km up to a specified upper limit. 
+
+cira.for        This file includes the subroutines and functions for computing 
+                the COSPAR International Reference Ionosphere (NRLMSIS-00) 
+                neutral temperature and densities. 
+
+igrf.for        This file includes the subroutines for the International
+                Geomagnetic Reference Field (IGRF).
+
+dgrf%%%%.dat    Definitive IGRF coefficients for the years 1945 to 2000 in steps
+                of 5 years (%%%%=1945, 1950, etc.)(ASCII).
+igrf%%%%.dat    Prelimenary IGRF coefficients for most recent year (ASCII).
+igrf%%%%s.dat   IGRF coefficients for extrapolating 5 years into the future (ASCII).
+
+iritest.for 	Test program indicating how to use of the IRI subroutines. 
+                Requires irisub, irifun, iritec, iridreg, igrf,and cira.
+                
+iriorbit.for	Simple program for calculating IRI parameters along an orbit
+iriorbitmax.for Program to calculate F2 peak parameters along an orbit.
+
+ig_rz.dat       This file(s) contains the solar and ionospheric indices (IG12, Rz12) 
+                for the time period from Jan 1958 onward. The file is updated 
+                quarterly. It is read by subroutine tcon in irifun.for (ASCII). 
+               
+apf107.dat      This file provides the 3-hour ap magnetic index and F10.7 daily
+                81-day and 365-day index from 1960 onward (ASCII).
+
+CCIR%%.ASC,     Coefficient files for the global representation of the F2 peak
+   URSI%%.ASC	peak parameters (foF2, M3000) where %% = Month+10 (ASCII). CCIR is
+                the model recommended by the International Committee Consultative  
+                on Radiocommunication (CCIR) of the International Union of 
+                Telecommunication (ITU). URSI is the model recommended by the 
+                International Union of Radio Science. IRI recommends the CCIR
+                model for the continents and the URSI model for the ocean areas.
+                If a single model is needed globally URSI is recommended.
