LAST WEEK
The Last Week rainfall total represents the amount of rain that has been collected from Monday 12:00 AM to
Sunday 11:59 PM OF THE PREVIOUS WEEK. The Last Week value will update each Monday at 12:00 AM to reflect
the last full week’s total. Monday is used as this is the start date for international and business planning calendars.
Example: If today is Wednesday, rainfall that occurs today will not be included in the Last Week value until Monday
at 12:00 AM.
Note: This value will be 0.00 until a full week has been recorded.

update on the first day of the month 12:00 AM to reflect the last calendar month’s total.
Example: If today is the 15
th
of September, rainfall that occurs today will not be included in the Last Month value
until 12:00 AM on the first day of October.
Note: This value will be 0.00 until a full month has been recorded.
TOTAL
The total rainfall measurement is a stored value that continues to increment until it is reset. If you reset the other
rainfall measurements, the total will not be reset.
The total is calculated independently of the other rainfall amounts. Therefore, due to the rounding
calculations used to generate these values, daily, weekly and monthly totals recorded and tracked over
time may be slightly different than the grand totals shown in this field.
The data tab rounds conservatively and therefore displays a lower total than the Current Weather tab. The
history data eliminates rounding differences for analysis use.
