title: Arctic Global Radiation (AGR) Data Set, Version 1.0

description: Radiation data were compiled and computed from many sources in the Arctic to produce a two-part Arctic Global Radiation (AGR) data set. The first part includes a time series of monthly fluxes from land stations, ocean drifting stations and empirically derived long-term climatological estimates from earlier Russian studies. While many of the station time series are quite short, some span over 40 years. Data are provided for the region north of 60 degrees N. The second part is a long-term monthly mean gridded climatology for the region north of 65 degrees N, based on the AGR-1 data set. For the most comprehensive information on this data set, read the extensive documentation.

As part of the data processing of Arctic Rapid Integrated Monitoring System (ArcticRIMS) based at the Water Systems Analysis Group (WSAG), University of New Hampshire all data sets have been aggregated to multiple temporal and spatial resolutions. The data is presented in 24 sub-datasets of different spatial and temporal aggregations.

title: An Analysis of the Carbon Balance of the Arctic Basin from 1997 to 2006, Version 1.0

description: These data sets are the results of a model-data analysis of the contemporary C balance of the Arctic system. CO2 and CH4 exchange between the terrestrial ecosystems of the basin and the atmosphere, along with the export of dissolved organic C (DOC) to the Arctic Ocean, were estimated using the Terrestrial Ecosystem Model (TEM). The TEM considers the effects of a number of factors on its simulations of C dynamics including changes in atmospheric CO2, tropospheric ozone, nitrogen deposition, climate, and disturbance/land use including fire, forest harvest, and agricultural establishment/abandonment. We used the methane dynamics module of TEM (MDM-TEM) to estimate the exchange of CH4 with atmosphere of both wetlands. The MDM-TEM considers the effects of a number of factors on its simulations of CH4 dynamics including the area of wetlands, fluctuations in the water table of wetlands, temperature, and labile carbon inputs into the soil solution derived from the net primary production (NPP) estimates of TEM. The results of these simulations were compared with estimates of CO2 and CH4 exchange from atmospheric inversion models and with observations of terrestrial C export from Arctic watersheds. The simulated transfer of land-based C to the Arctic Ocean was compared against estimates based on a sampling of DOC export from major Arctic rivers (McClelland et al., 2008). We summarize our estimates of surface-atmosphere CO2 and CH4 exchange for the land and ocean area matching the three high-latitude regions defined in the Transcom 3 model experiments (Gurney et al., 2002), namely the Boreal North America, Boreal Asia and Northern Ocean regions.

title: Photosynthetic parameters and nutrient content of trees at the Panama crane sites.

description: This data package contains leaf chemistry and photosynthetic traits data from trees within the NGEE Tropics Parque Natural Metropolitano (PA-PNM) and Bosque Protector San Lorenzo (PA-SLZ) sites in Panama. Photosynthetic parameters including maximum photosynthesis, Vcmax, Jmax, and TPU, were calculated from A/Ci curves. Foliar nitrogen and phosphorus concentrations and leaf mass per unit leaf area of the leaves also were determined. The plants that were sampled were classified as to species, family, order, clade, and growth form (tree, liana, perennial herb, or other). Wood density of the tree and the source of that data also are included. Included in this data package is a zip file with a single Excel data file and CSV copies.

title: North Pole Environmental Observatory (NPEO) Weather and Radiation Buoy Data, Version 1.0

description: This data set includes in situ air pressure, wind, temperature, longwave radiation, and shortwave radiation measurements. Data were recorded from 27 April 2002 by weather stations and radiometers on drifting buoys near the North Pole that were deployed by the Pacific Marine Environmental Laboratory (PMEL). A lack of solar energy, which is needed to power the radiometer batteries, rendered some data useless after mid-to-late September. The North Pole Environmental Observatory (NPEO) is a year-round, automated scientific observatory, deploying various instruments each April in order to learn how the world's northernmost sea helps regulate global climate. It consists of a set of unmanned scientific platforms that record oceanographic, cryospheric, and atmospheric data throughout the year. Data are in ASCII text format.

title: Banks Island July 2003 Field Report, Version 1.0

description: A group of 19 researchers and students from the University of Alaska Fairbanks and other U.S. and Canadian organizations gathered at Green Cabin, northern Banks Island in July 2003. The team was interested in the interactions between the frost-boil heave processes, the soil, and the vegetation; and how complex interactions between these elements vary along the Arctic bioclimate gradient. A major goal of the project is to develop models that can help explain how frost heave patterns, soils and vegetation will respond to climate change.

title: Circumpolar Flaw Lead (CFL) Photosynthesis-Irradiance Experiments, Version 1.0

description: The objective of the Circumpolar Flaw Lead (CFL) project is to examine how physical changes affect biological processes within the flaw lead. The CFL system is formed when the central pack ice (which is mobile) moves away from coastal fast ice, opening a flaw lead. The CFL forms in the fall and continues as thin ice or open water throughout the winter. The flaw lead is circumpolar, with recurrent and interconnected polynyas occurring throughout the Arctic. The overarching objectives of the CFL project were to contrast the physical and biological systems of the flaw lead open water and thin ice to the adjacent landfast ice cover. The system will be studied throughout its yearly cycle, to determine the effects of global warming. This data set contains results of photosynthesis-irradiance experiments. This dataset has the data formatted as an Excel document and as a CSV document (delimited by tabs and double quotes).
