This is my personal homepage within NASA Goddard Space Flight
Center in Greenbelt, Maryland. Although personal homepages within
NASA are allowed and even encouraged, including things "personal" or
links to websites outside of NASA are subject to strict guidelines.
This homepage provides a listing of several NASA and non-NASA
links to obtain useful data for Earth Science and Space Science
applications. This webpage also provides several IDL and Fortran
routines which some may find useful in mathematics and science
including trend analysis.

TREND ANALYSIS SOFTWARE, ETC.:

MULTIPLE LINEAR REGRESSION ROUTINES (TREND ROUTINES, ETC.)
The trend analysis code originated from Ziemke et al. [1997] (PDF file, 4.8 Mb)
which used a Monte Carlo statistical approach. The multi-variate statistics
built into the trend code can be turned off and replaced by a Monte
Carlo method by adding random noise to the independent proxies.

FORTRAN CODE for solving general N X N linear system
problems (i.e.,solves AX=B using Gauss-Jordan method).

FORTRAN CODE for numerically solving ordinary differential equations (ODE's)
using a coupled Runge-Kutta method. This program shows one example of a 3rd-order ODE
and prints the results to an ASCII table which can be plotted using an IDL PLOTTING PROGRAM.
The IDL program generates a postscript IMAGE. for this example. Here are three
more EXAMPLES . JPEG image #1 and #2 coincide with the first two extra examples.

FORTRAN CODE for Empirical Orthogonal Function (EOF) analysis of data.

FORTRAN CODE for Fast Fourier Transform analysis of data. The first step
of Fourier analysis is to determine prime number factorization of the time series
length (Here is a FORTRAN CODE for providing prime number factorization). Here is
also a FORTRAN CODE for listing prime numbers.
