Hi Guys
Thanks for your help so far, much appreciated. The formula works a treat. However the only problem i have is with that formula i would have to calculate the sum of positive degrees for each day individually (because I need 365 indvidual positive degree sums) which could take some time, and i may have to repeat the process for more years later on.
So with the =SUMIF(F1:F24,"0",F1:F24) formula when i drag the result down the next box changes to =SUMIF(F2:F25,"0",F2:F25)
Is there a way of telling excel to jump to next set of 24 hours when you drag the result down e.g the box underneath would contain =SUMIF(F25:F48,''0'',F25:48) and so on?
Thanks again
Ryan

Hi Pecoflyer,
The third argument of SUMIF is optional, if the 1st and 3rd ranges are
the
same you can ignore the 3rd argument.

Hi,
supposing temp of deg is not included and your data for a given day
is
in cells A1 to A24, follwoing wll give the sum of daily positive
temps
:
=sumif(a1:a24,"0",a1:a24)
You ca then multiply this outcome with the meltfactor and area

Hi
For a project I am doing university I need to produce a basic ice
melt
model. I have got hourly temperature data for a whole year from a
certain location and area data from a glacier I am looking at,
which
has been broken down to several elevation bands each containing
the
area of ice present in that band.
Basically I need the model first to calculate the sum of postive
degrees for each day of the year (so this would add together all
the
temperature data above 0 for each day). This would leave me with
365
postive degree day factors (DDF).
Each of these DDF's then need to be multiplied by a Meltfactor
(say
0.06) and then multiplied by the area of a selceted elevation band
(DDF x 0.06) x Area
I am still a bit of a novice when it comes to all things excel so
Im
struggling a bit with this one. Its been suggested that I should
use
VBA but to be honest i dont know where to start. Any useful tips
etc
would be much appreciated.
Cheers
Ryan
