Climate dataset or project
Collections of airborne sand are obtained at the 15 NPP sites and the Geomet site. The collections are taken using BSNE collectors. The collectors are turned into the wind with wind vanes. The amount of material collected corresponds to the horizontal flux at the height of the collector and the opening area of the collector and the duration of the sampling time. The five heights of the BSNE collectors above the soil surface are 5, 10, 20, 50, and 100 centimeters for every location where samples are taken. The hypothesis of the experiment is that the vertical flux of the particles smaller than 10 micrometers is a constant ratio of the horizontal sand flux. The objectives of the experiment are to find patterns of sand flux rates as affected by soil and vegetation.
This data set is comprised of daily precipitation totals, in inches, measured by Belfort
Instruments weighing rain gauges at 58 locations on the Jornada Experimental Range.
Locations and the dates during which data were collected at them were generally project-oriented.
See comment section (#20) for start and end dates for each location.
Days on which data could not be obtained (due to equipment failure, user error, and/or
other reasons) are flagged as missing within this dataset. As of 31 December 2008 they
comprised 1,270 of the total 291,465 records, which is less than 0.44% of the data set.
Precipitation at 1 minute intervals for rain gauges 2-5 with R1 excluded due to periods of interruption. Spatially averaged rainfall over the watershed is calculated in this dataset based on relative coverage of each rain gauge determined from a Theissen polygon map.
Estimated daily precipitation is calculated for each of 15 aboveground net primary productivity (ANPP) sites located in the 5 dominant vegetation zones on the Jornada Basin. The 15 sites were formally established in 1989 as LTER Study 268, but these rainfall estimates begin in 1980 using the closest rain gauge that provides a minimum resolution of daily precipitation data. The Methodology section describes this in detail. The rain gauges are detailed inthe file raingauge_picks.csv.
This ongoing dataset contains monthly precipitation measurements from a network of standard can rain gauges at the Jornada Experimental Range in Dona Ana County, New Mexico, USA. Precipitation physically collects within gauges during the month and is manually measured with a graduated cylinder at the end of each month. This network is maintained by USDA Agicultural Research Service personnel. This dataset includes 39 different locations but only 29 of them are currently sampled. Other precipitation data exist for this area, including event-based tipping bucket data with timestamps, but do not go as far back in time as this dataset.
