Greetings out there in NTN land. We are entering the hot and sticky part of summer here. Take plenty of water out with you on your journey to the field site. NEW Collector Decal – In this mailing you’ll find the newest version of the ID decal for your collector. Please apply it to the NTN collector as instructed below: 1) Use a paper towel to wipe the collector surface clean. 2) Print your SITE ID plainly on the decal in the place provided using a permanent marker. 3) Carefully peel the paper off the decal (NOTE: these are hard to peel). 4) Position the decal on the side of the collector frame underneath the sensor as shown in Figure 1. 5) Let us know how the decal weathers and adheres over time.

Raingage chart installation: When placing a chart onto the raingage, align the lower pen with the local time. Due to the pen off-set, make sure that the lower pen is aligned with the time NOT the upper pen or errors can occur in the interpretation of the daily precipitation data recorded by the lower pen (the midnight line used to separate the daily values will not be accurate). See Figure 3-21, note that the precipitation pen (lower) started at ~ 0700 (local time) and the event recorder pen (upper) ~ 0400. This offset is typical and must be maintained so that the precipitation pen can cross underneath the event recorder pen during heavy rainfalls. For more information, see page 3-9 of the NTN Site Operation Manual.

Hello! We are starting to cool off a bit here in central Illinois. We hope the dry part of summer is over. We’re looking forward to needed precipitation to recharge our groundwater levels before winter. Speaking of winter . . . WINTERIZING: The memo requesting the removal of the funnel and the addition of antifreeze to your Belfort raingage is enclosed. DO NOT WAIT. If you are getting cold temperatures, go ahead and winterize NOW! See section 5.2.2.1 of the Site Operation Manual or the procedure pages at the back of the CALendar. Call Scott if you have questions (800-952-7353)	Funnel & Gage Housing
NEW RAINGAGE STUDY: Six sites will soon be up-and-running with a new high technology raingage. USGS is sponsoring the work at these specially selected sites. The OTT Pluvio (from the Latin pluvia, for rain) is the raingage being tested. It is an all-electronic gage; it may be the gage that serves the NADP through the next 20 years. Want to know more?
