The Dataset's Variables and Attributes

Row Type Variable Name Attribute Name Data Type Value
attribute NC_GLOBAL access_formats String .htmlTable,.csv,.json,.mat,.nc,.tsv,.esriCsv,.geoJson
attribute NC_GLOBAL acquisition_description String * The cosine PAR value for yrday_gmt 151 year 2001 is an estimate, based on a conversion from data recorded by the QSR240 scalar sensor package.

* Latitude and longitude have been added to this data set by the Data Management Office. These positions are the noon (12:00 hour) positions reported in the ship's alongtrack data set.

* Scalar PAR data was extracted from the ship's alongtrack meteorological data set. The sensor package was mounted on ship's science mast.

attribute NC_GLOBAL instruments_0_acronym String PAR sensor
attribute NC_GLOBAL instruments_0_dataset_instrument_description String Photosynthetically Available Radiation, PAR (400-700nm). Cosine irradiance (EsPAR) sensors collect light impinging on a Teflon-coated diffuser and the response is proportional to the cosine of the angle of incidence.
attribute NC_GLOBAL instruments_0_dataset_instrument_nid String 4176
attribute NC_GLOBAL instruments_0_description String A PAR sensor measures photosynthetically available (or active) radiation. The sensor measures photon flux density (photons per second per square meter) within the visible wavelength range (typically 400 to 700 nanometers). PAR gives an indication of the total energy available to plants for photosynthesis. This instrument name is used when specific type, make and model are not known.

attribute NC_GLOBAL instruments_1_acronym String Radiometer
attribute NC_GLOBAL instruments_1_dataset_instrument_description String Biospherical Instruments GUV-500 is a 5-channel reference radiometer which typically measures cosine-corrected down welling irradiance at 305, 320, 340, 380nm.
Biospherical Instruments QSR250 system measures a single channel of scalar irradiance (PAR) and is appropriate for applications independent of the directionality of the light field, such as measurements of the flux available for photosynthesis.
attribute NC_GLOBAL instruments_1_dataset_instrument_nid String 4177
attribute NC_GLOBAL instruments_1_description String Radiometer is a generic term for a range of instruments used to measure electromagnetic radiation (radiance and irradiance) in the atmosphere or the water column. For example, this instrument category includes free-fall spectral radiometer (SPMR/SMSR System, Satlantic, Inc), profiling or deck cosine PAR units (PUV-500 and 510, Biospherical Instruments, Inc). This is a generic term used when specific type, make and model were not specified.

attribute NC_GLOBAL projects_0_description String The fundamental objectives of United States Global Ocean Ecosystems Dynamics (U.S. GLOBEC) Program are dependent upon the cooperation of scientists from several disciplines. Physicists, biologists, and chemists must make use of data collected during U.S. GLOBEC field programs to further our understanding of the interplay of physics, biology, and chemistry. Our objectives require quantitative analysis of interdisciplinary data sets and, therefore, data must be exchanged between researchers. To extract the full scientific value, data must be made available to the scientific community on a timely basis.
