Data and scripts for Fudan-NSA cloud fraction scheme
<p>Data and scripts for preparing the Fudan-NSA cloud fraction scheme.</p>
BOREAS TF-08 NSA-OJP and SSA-OBS Ceilometer Data
The BOREAS TF-08 team used ceilometers to collect data on the fraction of the sky covered with clouds and the cloud height. Included with these data is the surface-based lifting condensation level, derived from temperature and humidity values acquired at the flux tower at the NSA-OJP site. Ceilometer data were collected at the NSA-OJP site in 1994 and at the NSA-OJP and SSA-OBS sites in 1996.
BOREAS TF-08 NSA-OJP Tower Flux, Meteorological, and Soil Temperature Data
The BOREAS TF-08 team collected energy, CO2, and water vapor flux data at the BOREAS NSA-OJP site during the growing season of 1994 and most of the year for 1996.
BOREAS DEM Data over the NSA-MSA and SSA-MSA in AEAC Projection
These data were derived from the original DEMs produced by the BOREAS HYD-08 team. The original DEMs were in the UTM projection, while this product is projected in the AEAC projection (see Section 7 for further projection details). The pixel size of the data is 100 meters, which is appropriate for the 1:50,000- scale contours from which the DEMs were made. The original data were compiled from information available in the 1970s and 1980s. This data set covers the two MSAs that are contained within the SSA and the NSA.
BOREAS TE-09 in Situ Diurnal Gas Exchange of NSA Boreal Forest Stands
The gas exchange data of the Boreal Ecosystem-Atmosphere Study (BOREAS) Northern Study Area (NSA) were collected to characterize diurnal gas exchange and water potential of two canopy levels of five boreal canopy cover types: young and old jack pine (Pinus banksiana Lamb.), old aspen (Populus tremuloides Michx.), and lowland and upland black spruce (Picea mariana (Mill) B.S.P.). These data were collected between 27-May-1994 and 17-Sep-1994. The purpose of this study was threefold: 1) to provide in situ gas exchange data that will be used to validate models of photosynthetic responses to light, temperature, and carbon dioxide (CO2); 2) to compare the photosynthetic responses of different tree crown levels (upper and lower), and 3) to characterize the diurnal water potential curves for these sites to get an indication of the extent to which soil moisture supply to leaves might be limiting photosynthesis.
BOREAS Follow-On FLX-01 NSA-OBS Tower Flux, Meteorological, and Soil Temp. Data
The BOREAS Follow-On FLX-01 team collected tower flux, surface meteorological, and soil temperature data at the BOREAS NSA-OBS site continuously from March 1994 through December 1998. Data from March 1994 through October 1996 are included in the BOREAS TF-03 effort while data from the end of October 1996 through December 1998 are included in the BOREAS Follow-on FLX-01 effort.
BOREAS TE-09 in situ Understory Spectral Reflectance within the NSA
Spectral reflectance of the forest understory at the ground level, in three boreal forest sites of Northern Manitoba (56 degrees N latitude and 98 degrees W longitude), were obtained and analyzed. The objective of the study was to estimate light levels inside the forest canopy and to link these estimates with airborne images taken above the canopy, in order to tie the photosynthetic experiments and models with the remotely sensed measurements. The Boreal Ecosystem-Atmospheric Study (BOREAS) Terrestrial Ecosystem (TE)-09 project contained several sub-projects designed to work together to meet this goal: a high-resolution canopy modeling component, extensive measurements of canopy architecture and structure, photometric measurements inside the canopy, and spectral measurements of both the canopy and the understory.
BOREAS TGB-01 CH4 Concentration and Flux Data from NSA Tower Sites
The BOREAS TGB-01 team made numerous measurements of trace gas concentrations and fluxes at various NSA sites. This data set contains half-hourly averages of ambient methane (CH4) measurements and calculated fluxes for the NSA-TF in 1996 and the NSA-BP and NSA-OJP tower sites in 1994. The purpose of this study was to determine the CH4 flux from the study area by measuring ambient CH4 concentrations. This flux can then be compared to the chamber flux measurements taken at the same sites.
BOREAS Follow-On FLX-01 NSA-OBS Derived Data - NEE, GEE, and Respiration
The BOREAS Follow-On FLX-01 team derived NEE, GEE, and Respiration using measured tower C02 flux measurements taken at the NSA-OBS site. The data provided contain half-hourly measurements as well as 4 and 5 day binned data sets. The derived data covers the period from March 1994 through the end of 1998.
BOREAS TE-09 NSA Leaf Chlorophyll Density Data
The Boreal Ecosystem-Atmosphere Study (BOREAS) Terrestrial Ecology Team #9 (TE-09) provided several data sets containing information about the state and response of boreal forest tree species. This data set contains information on the spatial density of chlorophyll in the leaves of three boreal tree species collected at five different sites at various times during 1994.
BOREAS RSS-07 Landsat TM LAI Images of the SSA and NSA
The BOREAS RSS-07 team used Landsat TM images processed at CCRS to produce images of LAI for the BOREAS study areas. Two images acquired on June 6 and August 9, 1991 were used for the SSA, and one image acquired on June 9, 1994 was used for the NSA. The LAI images are based on ground measurements and Landsat TM RSR images. The data are stored in binary image-format files. Companion files include example thumbnail images that may be viewed and the image data files downloaded using a convenient viewer utility.
BOREAS TGB-06 Soil Methane Oxidation and Production from NSA BP and Fen Sites
The BOREAS TGB-06 team collected soil methane measurements at several sites in the SSA and NSA. This data set contains soil methane consumption (bacterial CH4 oxidation) and associated 13C fractionation effects in samples that were collected at various sites in 1994 and 1996 from enclosures (chambers). Methane 13C data in soil gas samples from the NSA YJP and OJP sites for 1994 and 1996 are also given. Additional data on the isotopic composition of methane (carbon and hydrogen isotopes) produced in the NSA beaver ponds and fen bog in 1993 and 1994 are given as well.
BOREAS TGB-04 Water and Sediment Temperature Data over the NSA-BP (Beaver Pond)
The BOREAS TGB-04 team collected several data sets in support of their flux tower measurements at the NSA Beaver Pond site. This data set contains water and sediment temperature data collected from May to September 1994.
BOREAS TGB-04 NSA-BVP Tower Flux and Meteorological Data
The BOREAS TGB-04 team measured the exchange of heat, water, and CO2 between a boreal forest beaver pond and the atmosphere in the NSA for the ice-free period of BOREAS. The data cover the period of May 28 to September 18, 1994.
BOREAS TGB-12 Radon-222 Activity Data over the NSA
The BOREAS TGB-12 team made measurements of soil carbon inventories, carbon concentration in soil gases, and rates of soil respiration at several sites to estimate the rates of carbon accumulation and turnover in each of the major vegetation types. Sampling strategies for soils were designed to take advantage of local fire chronosequences, so that the accumulation of C in regrowing mosses could be determined. All the data are used to (1) calculate the inventory of C and N in moss and mineral soil layers at NSA sites (2) determine the rates of input and turnover (using both accumulation since the last stand-killing fire and radiocarbon data) and (3) link changes in soil respiration rate to shifts in the 14C content of soil CO2 to determine the average 'age' respired CO2. These 222Rn activity data were collected from 15-NOV-1993 to 16-AUG-1994 over the NSA sites.
BOREAS HYD-08 DEM Data over the NSA-MSA and SSA-MSA in UTM Projection
These DEMs were produced from digitized contours at a cell resolution of 100 meters. Vector contours of the area were used as input to a software package that interpolates between contours to create a DEM representing the terrain surface. The vector contours had a contour interval of 25 feet. The data cover the BOREAS MSAs of the SSA and NSA and are given in a UTM map projection.
BOREAS TE-20 Supplementary Site Information For NSA Tower Sites
The BOREAS TE-20 team collected several data sets for use in developing and testing models of forest ecosystem dynamics. This data set and documentation were compiled from field notes and other information provided by Hugo Veldhuis, who did the original soils mapping in the field during 1994. The information here describes the soils and landscape characteristics of the NSA-MSA and tower sites.
BOREAS TGB-03 Dissolved Organic Carbon Data from the NSA
The BOREAS TGB-03 team collected Dissolved Organic Carbon (DOC) data during the summer of 1994 in the Northern Study Area. The purpose of this work was to establish the major sources, sinks and fluxes of dissolved organic carbon (DOC) in the Northern Study Area. Data on DOC concentrations taken from samples representing the major sources and sinks were to be combined with hydrologic measurements (e.g. precipitation, stream flow etc.) to calculate DOC fluxes.
BOREAS TF-03 Automated Chamber CO2 Flux Data from the NSA-OBS
The BOREAS TF-03 and TGB-01 teams collected automated CO2 chamber flux data in their efforts to fully describe the CO2flux at the NSA-OBS site. This data set contains fluxes of CO2 at the NSA-OBS site measured using automated chambers. In addition to reporting the CO2flux, it reports chamber air temperature, moss temperature, and light levels during each measurement. The data set covers the period from 23-Sep-1995 through 26-Oct-1995 and from 28-May-1996 through 21-Oct-1996.
