NEW RAW DATA FORMAT FOR 2003
****************************************
In an effort to improve our service, we will be making a major change to the format
of our raw data files.
We had hoped to have these new formats available on Jan 1 2003.
Unfortunately they will not be ready until later this month.
We will provide an specific date for the switch over.
Watch this document for important updates :
**** WE PLAN TO HAVE THE NEW FORMAT AVAILABLE BY JAN 22 ****
All data for 2003 will be reprocessed and put into these new formats.
(Raw data files from 2002 and earlier will remain in the old original format.)
The Raw Hourly data will have two new values added to the end of each line of data:
Actual Vapor Pressure (hourly average) at data point position 17
Dewpoint (hourly average) at data point position 18
The hourly integrated heat unit value which was at data point position 17
will be removed due to lack of use. The more widely accepted sine curve heat unit
value can still be found in the raw daily data.
Each hourly line will have a total of 18 values.
The Raw Daily data will have three new values added to the end of each line of data:
Reference Evapotranspiration (ETo) by Penman-Monteith equation, at data point position 26
Actual Vapor Pressure (daily mean at data point position 27
Dewpoint (daily mean) at data point position 28
Also note that the positions of the original AZMET ETo and heat unit values
have been transposed from the order of previous years.
Each daily line will have a total of 28 values.
Please see the lists below for a description of all values :
