Introduction to Programming

Objectives: This course provide a general overview of programming concepts, and specific introduction to Matlab, IDL(Interactive Data Language) and FORTRAN Language.  

I. Introductory Concepts 

 Week 1

Introduction: Unix background/overview, basic data structures.
PPT 1 | PDF
PPT 2 | PDF 

Week 2

Working in a Unix(-like) environment: Unix terminology, essential commands, shells(what they are/types/scripting),text editor(s).
PPT 2 | PDF 

Week 3

Network related topics: tunneling, vpn, ssh, ftp, scp, creating/maintaining a simple webpage (html), brief look at data format types.
The first part of class I'll cover the Unix/Linux commands left from last lecture.
The second part will be a demo illustrating many of these commands to transfer and work with data over a network.
Part of the process involves a nice opportunity to use a shell script.

Data sets
data.txt is a 41 x 41 block of data representing "elevation" the data set covers the area 24.0 N to 48 N and -122.0 W to -72 W with 0.6 degrees between each grid point in the meridional direction and 0.75 degrees between each grid poin in the zonal direction.
This dataset was obtained from D. Fanning

tas_gfdl.nc is a global surface temperature dataset from the Climate of the 20th Century simulations produced with the GFDL CM 2.0 GCM. This dataset was obtained from the PCMDI website.

Data sets
GP_precip.txt is timeseires of monthly mean Great Plains Preciptation
Extending from 1901-2002. This data set was derived from the CRU TS 2.1 preciptation data set.
hadcrut3gl.txt is a global combined land and  marine [sea surface temperature (SST) anomalies from HadSST2, see Rayner et al., 2006] temperature anomalies on a 5 x 5 degree grid-box basis.
anomalies are taken relative to the 1961-1990 base. The timeseires extends from
1850-present. For each year, the first row represents the monthly mean temperature anomalies and the second row represents the percent of the globe with data.
nino3.4_index.txt is a timeseires of the Nino 3.4 index. The timeseires extends from 1870-2002
sunspot_activity is a timeseries of the monthly mean international sunspot number from
http://www.ngdc.noaa.gov/stp/SOLAR/ftpsunspotnumber.html  The timeseries extends from 1850-present.
