   Abstract:

This primary purpose of this data set is to validate the LTER Weather Station tipping bucket rain gauge data. The dipstick rain gauge (DSRG) data is measured at least weekly during scheduled maintenance trips to the LTER Weather Station to maintain the evaporation pan water levels. During the summer months this may be twice a week. Additionally, DSRG data is collected after any rain event that requires the collection of the Wetfall/Dryfall precipitation buckets which are located about 10 meters from the DSRG. This is usually any amount greater than 0.02". DSRG data is also collected after very small events when personnel are in the vicinity.


   Additional information:

Located at Jornada LTER Weather Station about 2 meters from tipping bucket rain gauge. Jornada LTER Weather Station is located about 0.5 mile SE of NMSU Chihuahuan Desert Rangeland Research Center ranch headquarters.

   Methods:

field data sheets (3x5 index card)

   Methods:

To make a measurement from the dipstick rain gauge (standard can rain gauge): Lift off the top to the rain gauge. The dipstick is stored between the interior well and the gauge outer container. Ensure that the dipstick is clean and dry then slowly place the dipstick into the interior well while keeping it vertical. Quickly remove the dipstick and immediately read the depth in tenths of inches using the residual water mark. Record the date, depth in inches to 2 decimal places, and your initials on the 3x5 index card located on the inside wall of the dipstick rain gauge. Empty the water in the gauge; be patient and allow all the water to drain. A quick dump may leave measurable amounts of water that drain back down the side walls.

   Maintenance:

At least weekly or after a rain event.
