Development and Demonstration of a Method for GEO-to-LEO NDVI Transformation

open access: yesRemote Sensing, 2021
This study presents a new method that mitigates biases between the normalized difference vegetation index (NDVI) from geostationary (GEO) and low Earth orbit (LEO) satellites for Earth observation.

S2Looking: A Satellite Side-Looking Dataset for Building Change Detection

open access: yesRemote Sensing, 2021
Building-change detection underpins many important applications, especially in the military and crisis-management domains. Recent methods used for change detection have shifted towards deep learning, which depends on the quality of its training data. The

EM models for evaluating rain perturbation on the NRCS of the sea surface observed near nadir [PDF]

open access: yesIEE Proceedings - Radar, Sonar and Navigation, 1998
The authors address the problem of evaluating the normalised radar cross section (NRCS) of the sea surface perturbed by the joint effect of rain and wind, when observed close to nadir. They present a model, based on the full wave theory, for evaluating such an NRCS when varying polarisation, frequency and incidence angle (not far from nadir) for ...

Retrieving aerosol in a cloudy environment: aerosol product availability as a function of spatial resolution [PDF]

open access: yesAtmospheric Measurement Techniques, 2012
The challenge of using satellite observations to retrieve aerosol properties in a cloudy environment is to prevent contamination of the aerosol signal from clouds, while maintaining sufficient aerosol product yield to satisfy specific applications.

Characterization of global near-nadir backscatter for remote sensing radar design [PDF]

open access: yesIEEE 1999 International Geoscience and Remote Sensing Symposium. IGARSS'99 (Cat. No.99CH36293), 2003
In order to evaluate side-lobe contamination from the near-nadir region for Ku-band radars, a statistical characterization of global near-nadir backscatter is constructed. This characterization is performed for a variety of surface types using data from TRMM, Seasat, and TOPEX. An assessment of the relative calibration accuracy of these sensors is also

A method for merging nadir-sounding climate records, with an application to the global-mean stratospheric temperature data sets from SSU and AMSU [PDF]

open access: yesAtmospheric Chemistry and Physics, 2015
A method is proposed for merging different nadir-sounding climate data records using measurements from high-resolution limb sounders to provide a transfer function between the different nadir measurements.

A study of the NOAA near-nadir Microwave Humidity Sounder brightness temperatures over Antarctica [PDF]

open access: yes2011 IEEE International Geoscience and Remote Sensing Symposium, 2011
Brightness temperatures from NOAA-18 and NOAA-19 MHS measurements are investigated over Antarctica to establish it as a natural vicarious calibration target for determination of the Inter-satellite/inter-sensor Calibration Biases (ICB) of the two MHS radiometers.

Algorithm theoretical baseline for formaldehyde retrievals from S5P TROPOMI and from the QA4ECV project [PDF]

open access: yesAtmospheric Measurement Techniques, 2018
On board the Copernicus Sentinel-5 Precursor (S5P) platform, the TROPOspheric Monitoring Instrument (TROPOMI) is a double-channel, nadir-viewing grating spectrometer measuring solar back-scattered earthshine radiances in the ultraviolet, visible ...
