Egypt regional humidity probability - Annex F - IEC 62552

The following data are based on weather data log of weather station of Cairo International Airport CAI HECA weather station number 623660 found in this link http://en.tutiempo.net/climate/ws-623660.html

The following table is approximate humidity probability Ri for Egypt during year 2016 to be used in Annex "F" in IEC 62552-3:2015. You can download the climate data of Cairo 2016 from this link https://drive.google.com/open?id=0BxLFp7fy6GivazZSanFDNDgxeEU

Assumptions:

[1] Measured temperatures are indoor

[2] Cairo weather is considered as Egypt weather

[3] 2017 weather is expected to be the same as 2016 weather
