Thermal Infrared Spectrometer for Earth Science Remote Sensing Applications—Instrument Modifications and Measurement Procedures
In this article we describe a new instrumental setup at the University of Twente Faculty ITC with an optimized processing chain to measure absolute directional-hemispherical reflectance values of typical earth science samples in the 2.5 to 16 μm range. A Bruker Vertex 70 FTIR spectrometer was chosen as the base instrument. It was modified with an external integrating sphere with a 30 mm samplin...
متن کاملFrequency-comb infrared spectrometer for rapid, remote chemical sensing.
We demonstrate real-time recording of chemical vapor fluc-tuations from 22m away with a fast Fourier-transform infrared (FTIR) spectrometer that uses a laser-like infrared probing beam generated from two 10-fs Ti:sapphire lasers. The FTIR's broad 9-12 microm spectrum in the "molecular fingerprint" region is dispersed by fast heterodyne self-scanning, enabling spectra at 2cm-1 resolution to be r...
متن کاملMeasurement science for climate remote sensing
The NIST role in supporting our Nation’s climate research is described. The assembly of climate data records over decadal time scales requires assimilating readings from a large number of optical sensors deployed in space and on the Earth by various nations. NIST, in partnership with NASA and NOAA, develops and disseminates the calibration tools and standards to ensure that the measurements fro...
متن کاملRadar Remote Sensing for Earth and Planetary Science
Among imaging sensors, RADAR, an acronym for RAdio Detection And Ranging, is generally used in different modes. The radar system transmits a microwave signal directing towards the region of interest and detects the signal backscattered by the surface. Due to long wavelength, microwave signal can penetrate through cloud cover, haze, dust and heavy rainfall. This property of microwaves helps in a...
متن کاملSpectral Analysis for Earth Science: Investigations Using Remote Sensing Data
Remote sensing in the earth sciences has grown remarkably over the last decade. This growth has been spurred by rapid advances in technology that have opened up new avenues of analysis and inquiry. Of these advances, the merging of spectroscopy and imaging has been the most important. Spectroscopy has been used as a quantitative tool in the laboratory for many years and there exists a wealth of...
