Dr. Neigh's recent work has focused on quantifying regional forest disturbances and biomass using a suite of multispectral sensors, spaceborne and airborne LiDAR and sub-meter commercial satellite data to characterize the productivity, structure and carbon content of land surface vegetation. He has extensive experience evaluating vegetation greening and browning trends, mapping land-cover change/biomass and modeled the terrestrial carbon-cycle with disturbance.

Harmonized Landsat and Sentinel-2 V2.0
Remote Sensing
https://hls.gsfc.nasa.gov/
The Harmonized Landsat and Sentinel-2 (HLS) project is a NASA initiative aiming to produce a seamless surface reflectance record from the Operational Land Imager (OLI) and Multi-Spectral Instrument (MSI) aboard Landsat-8/9 and Sentinel-2A/B remote sensing satellites, respectively. The HLS products are created from a set of algorithms: atmospheric correction, cloud and cloud-shadow masking, geographic co-registration and common gridding, bidirectional reflectance distribution function (BRDF) normalization, and bandpass adjustment. The HLS Version-2.0 data are available now with global coverage (except for Antarctica). With four sensors currently in this virtual constellation, HLS provides observations once every three days at the equator and more frequently with increasing latitude. The HLS project is a collaboration between NASA and USGS, with the science team at NASA Goddard Space Flight Center supported by USGS Earth Resources Observation and Science (EROS) Center on atmospheric correction, the production team at NASA Marshall Space Flight Center, and product archive at USGS.
