Dear all,
4 years ago, I have asked through this forum about Maximum length of dry spell. The formula provided by zbor is very useful for me to create a climate early warning for drought.
Now I would like to calculate "Number of days since a dry day" which is just a reverse from "Number of Days Since Last Rain" formula in the post#11
I have been try to modify the formula, but no luck. As I am not mastering in Excel, so I just try and error.
I have upload the example data through this link http://cl.ly/gQKD (I am sorry, I can't upload through attachment button).
RD = RainDay
1 = Rain
0 = Dry
Can anybody help me to solve the problem?
Thank you, Benny
