Documentation and Task Lists for 2003/2004

File description and task list for 2003-04 Cape Hallett Met Files:

o1=omit from level 1,

ok= no changes to get to level 1,

rclow= reverse temperatures to resistance and apply Rclow subroutine to R values using

                Steinhart-Hart equation. The form of the equation is: 1/ Temp = a + b( LnR) + c( LnR)^3; where,

a = 0.00084636, b = 0.00020627, c = 0.000000086958

bad= normally would be included in level 1 but number is bogus,

flag= reasonable number but needs a note attached concerning its collection:

 

Array I.D. meaning:

First and Second Digit

01 = Cape Hallett

 

Hardware Notes:

1)       Construct met station

2)       Download data at end of January
