Hi, I have started to learn some numerical math software. I am looking
for some physical data that I can use in order to get familiar with my
numerical software. For instance, I would like to get the data about
sun's temperature distribution(T=T(x,y,z,t)) or magnetic field. I am
interested in calculating divergence or curl of some data at each
point, so it would be very nice that the data has some associated
direction with it( like E field or maganetic field). My computer does
not have a huge hard drive( I only have 100 Mb left), so I can't
handle a huge data set. Could you give me any suggestions?
Thank you very much, and have a good day.



There is a lot of publically available data from the various instruments
of the SOHO spacecraft. It may not be in the form you want it but dig
around:

They do provide software for analysing the data too.
