WEATHER DATA FORMAT

INTRODUCTION
These data are placed in the following format to support IPM decision making in Oregon Contact Len Coop at coopl@bcc.orst.edu if you have questions or need for some other format.

Here is an example of the format. Following is an explanation of it.

 1996 CRVO             { Agrimet data proc. L Coop }
01 01 43.022 31.934 0.011 0.00
01 02 49.312 35.829 0.381 0.00
01 03 37.020 24.419 0.000 0.00
13

In the format above, there is a one line header for each year and station,
with comments placed at least 10 characters after the station name
(required). Station names may be up to 10 characters. The station names
used are the standard Agrimet 4 character names.

Then each day has one line with MONTH DAY MAX MIN RAINFALL DD50 as a complete
record. RAINFALL is optional. Other types of data such as soil MAX and MIN
are also optional. Comments may be placed after these fields, they will be
ignored by the IPM models. DD50 is the degree-days calculated using a lower threshold of 50 F,
no upper threshold, and a single triangulation calculation method.

NO MISSING days are allowed. ALL RECORDS should start with Jan 1st and not
skip any days. A '13' is currently used to terminate AGRIMET data. NO
BLANK lines are allowed in the files. 

NO missing data are allowed. If we
find missing data (a common occurrance), we fill it in with interpolated
data. You can recognize such filled in data because it will lack any
decimal digits. For example,

01 01 43.022 31     0.011 0.00

is missing the MIN temperature - it was interpolated here.  In the case of
rainfall data, we replace missing data with zeros. Trace data are given as
0.003 or -0.007 by Agrimet; we try to remove the minus signs (required hand
editing).
