For an instrument with limiting apertures and solid angles, it is the Radiance of the source that determines how much radiation passes through the instrument. By carefully matching the instrument with a source of appropriate Radiance, an optimum system can be designed. < Back to list of technical papers View PDF format >

Jun 19, 2018 . What is Photometry. Photometry is a subset of radiometry that only applies to the visible portion of the electromagnetic spectrum. While radiometry focuses on measuring radiant energy in terms of absolute power, photometry takes into account the response of the human eye and focuses on measur ing light in terms of perceived brightness.. Photometry is the "science …

The design of the Multispectral Instrument (MSI) on-board SENTINEL-2 has been driven by the requirement for large swath high geometrical and spectral performance of the measurements. The MSI measures the Earth's reflected Radiance in 13 spectral bands from VNIR to SWIR (Table 1). NOTE: The Bandwidth (nm) is measured at Full Width Half Maximum (FWHM).

Overview. Remote sensing instruments are of two primary types: Active sensors, provide their own source of energy to illuminate the objects they observe. An active sensor emits radiation in the direction of the target to be investigated. The sensor then detects and measures the radiation that is reflected or backscattered from the target.

Like the Elegia and Stellia, the Radiance is a circumaural (around-the-ear), closed-back design that connects to the source device with actual wires—no Bluetooth here! It comes with a 4-foot OFC (oxygen-free copper) 24 AWG cable with a 3.5mm plug and an adapter that converts it to a 1/4-inch plug.
To compare the irRadiance of different sources, one must take into account the distance from the source. A 50 cm distance is often used for such measurements. IrRadiance is a useful measure for applications where power must be delivered to large areas.
The MSI measures the Earth's reflected Radiance in 13 spectral bands from VNIR to SWIR (Table 1). The Bandwidth (nm) is measured at Full Width Half Maximum (FWHM).
The data assimilation system WRFDA was developed with 3DVAR, four-dimensional variational DA (4DVAR), and Hybrid (incorporating ensemble-produced background error in the variational framework) DA techniques at the National Center for Atmospheric Research (NCAR) [ Barker et al ., 2012 ].
The WRF-NMM model code contains an initialization program (real_nmm.exe; see Chapter 4 of the WRF-NMM User's Guide) and a numerical integration program (wrf.exe; see Chapter 5 of the WRF-NMM User's Guide for more details and references.) This program can be used to post-process both WRF-ARW and WRF-NMM forecasts and was designed to:
For more information on WRFDA, visit the WRFDA Users home page http://www.mmm.ucar.edu/wrf/users/wrfda/index.html The following bugs have been fixed: -BUFR libraries have been updated to allow WRFDA to read and assimilate NCEP PREPBUFR files of any endianness.
- CRTM V2.0.2 has been included as an internal library in WRFDA codes. Setting environmental variable CRTM to ANYTHING to activate the CRTM installation during WRFDA compilation.
