UMBS PROPHET Tower
UMBS PROPHET Tower
The PROPHET (Program for Research on Oxidants: PHotochemistry, Emissions, and Transport) tower and laboratory are located within a forested area on the University of Michigan Biological Station property. The tower is a 103 feet 5 inch tall, guyed stairway-type tower erected in December of 1996. A glass manifold reaches to 115 feet and delivers air samples to the laboratory for analysis. The Tower lab building is 20 x 30 x 10 feet and is insulated and supplied with heat and air conditioning (two 7.5 ton units). It has telephone and data line service and 3-phase power. The building is furnished with shelving, lab benches and a few computer desks.

|Ultraviolet Light Flux from Forest Floor||Ultraviolet light flux was measured at the forest floor at several locations on the UMBS property and along the vertical profile of the PROPHET Tower.|
|Bracken Fern (Pteridophyta Pteridium) root, rhizome, stem, frond, allometry||Contains information on bracken fern body part sizes from the frond to the rhizome for 22 ferns within 200 feet of the PROPHET site. Rhizomes were dug up at a maximum of 6 feet of their length and specimens were chosen to represent various frond sizes.|
|2010 Volatile Organic Compounds Measured at FASET and PROPHET Towers||Measurements of volatile organic compound (VOC) fluxes and concentrations were taken at the UMBS FASET and PROPHET atmospheric towers. These measurements along with computer modeling will characterize the effects of forest succession on VOC fluxes to the atmosphere. Measured VOCs are isoprene and...|
|Total OH (Hydroxyl) Reactivity Measurements for CABINEX 2009 campaign (Indiana University)||Total OH (hydroxyl) Reactivity Measurements for CABINEX 2009 campaign sampled at the PROPHET Tower at the University of Michigan Biological Station (UMBS). The data set focuses on ambient measurements of total OH reactivity near the forest floor. Total OH reactivity data is presented as...|
|Tropospheric oxidant measurements from the 2009 CABINEX campaign||Measurements of tropospheric oxidants HOx, ozone and water, as part of the 2009 CABINEX campaign at the University of Michigan Biological Station (UMBS). Samples were taken at the PROPHET facilities.|
|Isoprene, Methacrolein, and Methyl Vinyl Ketone at the PROPHET Tower in 2008||Measurements of ambient methyl vinyl ketone (MVK), methacrolein (MACR), isoprene, and total monoterpine (MT) concentrations taken at the University of Michigan Biological Station PROPHET Tower.|
|Volatile organic compound mass spectrometry measurements over a vertical forest canopy gradients||This study measured the concentration of acetaldehyde and acetone compounds across a vertical gradient within a mixed hardwood northern forest. Sampling took place at the University of Michigan Biological Station (UMBS) during the summer of 2008.|
|Soil emissions of oxygenated volatile organic compounds||Live vegetation is known to be a strong source of isoprene and acetone to the atmosphere while being both a source and a sink for acetaldehyde. However, the role of soil and decaying litter in the exchange of these compounds under ambient conditions is uncertain. In this study, we measured the...|
|Trace isotopes in rain, clouds and soil in Northern Michigan 2009||Trace isotope measurements of xx, xx, xx, in precipitation, clouds and soils near the University of Michigan Biological Station (UMBS) in the summer of 2009.|
|Glyoxal and formaldehyde measurements at the PROPHET mixed hardwood forest site in 2008 and 2009||Glyoxal and formaldehyde (HCOH) measurements collected from the University of Michigan Biological Station's PROPHET tower. Glyoxal measurements were taken from June 24 to July 22, 2008 and are reported in pptv. Glyoxal measurements were also taken from June 30 to August 8, 2009 as part of the...|
|Isoprene profile and flux measurements at the PROPHET mixed hardwood forest site in 2000-2003||Isoprene concentration and flux were measured at the University of Michigan Biological Station (UMBS) PROPHET and AmeriFlux towers in a mixed northern hardwood forest in 2000-2003. The isoprene concentration profiles sampling heights in 2000 were: 3.5, 7, 11, 14, 22, 31, and 46 meters above ground...|
