8. Data Collection & Evaluation The recorded solar irradiance and ambient temperature readings were collected every sixty days by transferring the data from the data logger directly to a laptop computer into a text data file "File""053 - Aqaba-Jordan\Aqaba 13-9-06.P0" "*EKO-21* serial number : 2307" "Identification text :Aqaba" "Start date : 22-Aug-06" "Start time : 8:08:19 AM" "Record interval : 00:10:00" "Sample interval : 00:00:03" "Readings : 3177" "No. channels : 2" "Channel specifications :" "No";"";" 0";" 1" "Minimum";"";"0";"-" "Maximum";"";"1372.36";" 360" "Units";"";"W/m2";"C" "Quantity";"";"Solar Rad nr 041278";"Temperature Air" "date";"time";"avg 0";"log 1" "22-Aug-06";"8:08:19 AM";503;33.8; "22-Aug-06";"8:18:19 AM";537;34.0; "22-Aug-06";"8:28:19 AM";567;34.1; "22-Aug-06";"8:38:19 AM";600;33.9; "22-Aug-06";"8:48:19 AM";630;34.5; "22-Aug-06";"8:58:19 AM";659;34.7; "22-Aug-06";"9:08:19 AM";685;35.0; Raw data sample file
