Hello:

I have a daily timeseries data for 10 stations which are in foll. format:

year month day value

1970 1 1 12

1970 1 2 24

...............................

2010 12 31 34

This contains daily time series data from 1st January 1970 to 31st December 2010 with leap and non leap years. How to check for stations with (i) 12 months' record availability for each year record (ii) For each month at least 80% or more daily data availability?

But how do I check if each of the month contains at least 80% or more data availability. I have to run the loop, so I can't go for visual way? And each case, starting and ending year may vary depending on stations.
