These measurements are at nominal wavelengths of 415, 500, 615, 673, 870, and 940 nm. The measur ements are made at a user-specified time interval, usually about one minute or less. The sampling rate for the Atmospheric Radiation Measurement (ARM) Climate Research Facility MFRSRs is 20 seconds. From such measurements, one may infer the atmosphere's op tical depth at the wavelengths mentioned above. In turn, these optical depths may be used to derive information about the column abundances of ozone and water vapor (Michalsky et al. 1995), as well as aerosol (Michalsky et al. 1994) and other atmospheric c onstituents. mfrsr handbook is available at: http://www.arm.gov/publications/tech_reports/handbooks/mfrsr_handbook.pdf 20051125 20070108 Completed None 2.174 2.174 13.477 13.477 science keywords Atmospheric Radiation Measurement DOE ARM ARM ARM Observed Data Radiometric Radiometric shortwave narrowband Radiation, shortwave, diffuse hemispheric irradiance, 415 nm wavelength Radiation, shortwave, diffuse hemispheric irradiance, 500 nm wavelength Radiation, shortwave, diffuse hemispheric irradiance, 615 nm wavelength Radiation, shortwave, diffuse hemispheric irradiance, 673 nm wavelength Radiation, shortwave, diffuse hemispheric irradiance, 870 nm wavelength Radiation, shortwave, diffuse hemispheric irradiance, 940 nm wavelength Radiation, shortwave, direct normal irradiance, 415 nm wavelength Radiation, shortwave, direct normal irradiance, 500 nm wavelength Radiation, shortwave, direct normal irradiance, 615 nm wavelength Radiation, shortwave, direct normal irradiance, 673 nm wavelength Radiation, shortwave, direct normal irradiance, 870 nm wavelength Radiation, shortwave, direct normal irradiance, 940 nm wavelength Radiation, shortwave, hemispheric irradiance, 415 nm wavelength Radiation, shortwave, hemispheric irradiance, 500 nm wavelength Radiation, shortwave, hemispheric irradiance, 615 nm wavelength Radiation, shortwave, hemispheric irradiance, 673 nm wavelength Radiation, shortwave, hemispheric irradiance, 870 nm wavelength Radiation, shortwave, hemispheric irradiance, 870 nm wavelength Shortwave narrowband diffuse downwelling irradiance Shortwave narrowband direct normal irradiance Shortwave narrowband total downwelling irradiance nimmfrsrM1.a0 nimmfrsrM1.b1 nimmfrsrS1.a0 nimmfrsrS1.b1 Instrument ARM Multifilter Rotating Shadowband Radiometer Place Keywords nim.M1: Niamey, Niger; Mobile Facility ,Niamey, Niger nim.S1: Niamey, Niger; Mobile Facility ,Niamey, Niger-Ancillary Gary Hodges Gary.Hodges@noaa.gov Mailing and Physical Address Boulder CO 80305-3328 USA N/A Oak Ridge National Laboratory (ORNL), Oak Ridge, Tennessee, USA ARM Archive User Services +1-865-241-4851 armarchive@ornl.gov url visualization http://www.archive.arm.gov/arm/Thumbnail2.jsp?siteCode=nim&instClass=mfrsr Public image thumbnail http://www.archive.arm.gov/quicklooks/2006/nim/nimmfrsrM1.b1/nimmfrsrM1.b1.200603/.icons/nimmfrsrM1.b1.20060331.000000.diffuse_hemisp_narrowband_filter1.png Public Atmospheric Radiation Measurement (ARM) Program Data Sets. 1993-Ongoing.
