This table contains the sub-canopy meteorological data collected by HYD-3.

BOREAS HYD-03 Subcanopy Radiation Data

공공데이터포털

The BOREAS HYD-03 team collected several data sets related to the hydrology of forested areas. This data set contains solar radiation measurements from several pyranometers (solar radiometers) placed on the snow surface in jack pine (1994) and black spruce and aspen forests (1996). An array of radiometers was used to collect data for 3-4 consecutive days in each forest type to study the hypothesis that energy transfer and snow water equivalent would vary spatially as a function of canopy closure. The quality of the data is good, because the days were generally clear and the radiometers were checked daily to remove anything that landed on the radiometers.

BOREAS HYD-03 Subcanopy Meteorological Data

공공데이터포털

The BOREAS HYD-03 team collected several data sets related to the hydrology of forested areas. This data set includes measurements of wind speed and direction; air temperature; relative humidity; and canopy, trunk, and snow surface temperatures within three forest types. The data were collected in the SSA-OJP (1994) and SSA-OBS and SSA-OA (1996). Measurements were taken for 3 days in 1994 and 4 days at each site in 1996. These measurements were intended to be short term to allow the relationship between subcanopy measurements and those collected above the forest canopy to be determined. The subcanopy estimates of wind speed were used in a snow melt model to help predict the timing of snow ablation.

BOREAS HYD-01 Under Canopy Precipitation Data

공공데이터포털

Contains the under canopy precipitation data that was collected in 1994, 1995, 1996 and 1997 by the HYD-01 group at the various tower sites.

BOREAS TE-05 Surface Meteorological & Radiation Data

공공데이터포털

The BOREAS group TE-05 collected measurements in the NSA and SSA on gas exchange, gas composition and tree growth. Measurements of meteorological data, including air and soil temperature, RH, and PPFD were 30-minute intervals during the 1994 IFCs at various sites in the BOREAS NSA and SSA.

BOREAS RSS-14 GOES-7 Level-2 Shortwave and Longwave Radiation Images

공공데이터포털

This data set contains images of shortwave and longwave radiation at the surface and top of the atmosphere derived from collected GOES-7 data. The data cover the time period of 05-Feb-1994 to 20-Sep-1994. The images missing from the temporal series were zero-filled to create a consistent sequence of files.

BOREAS TGB-05 CO2, CH4, and CO Chamber Flux Data over the NSA

공공데이터포털

The BOREAS TGB-05 team collected a variety of trace gas concentration and flux measurements at several NSA sites. This data set contains carbon dioxide (CO2), methane (CH4), and carbon monoxide (CO) chamber flux measurements conducted in 1994 at upland forest sites that experienced stand- replacement fires. These measurements were acquired to understand the impact of fires on soil biogeochemistry and related changes in trace gas exchange in boreal forest soils. Relevant ancillary data, including data concerning the soil temperature, solar irradiance, and information from nearby unburned control sites, are included to provide a basis for modeling the regional impacts of fire and climate changes on trace gas biogeochemistry.

BOREAS TE-05 Surface Meteorological & Radiation Data

공공데이터포털

Contains meteorological data collected during field campaigns by TE-05.

BOREAS HYD-01 Under Canopy Precipitation Data

공공데이터포털

Under-canopy precipitation measurements were made by the BOREAS HYD-01 science team in 1994, 1995, and 1996 at various flux tower sites in the NSA and SSA. In 1994, these data were collected at the NSA-OJP, NSA-YJP, SSA-OJP, and SSA-YJP sites. Starting in 1995 and ending in 1997, data were collected at the NSA-OBS, NSA-OJP, NSA-YJP, and SSA-OA. These data were collected to support HYD-01 research by measuring the amount of water that falls through the canopy and is intercepted by the ground or moss. These data coincide with volumetric soil moisture measurements made by HYD-01.
