The Effects of VIIRS Detector-Level and Band-Averaged Relative Spectral Response Differences Between S-NPP and NOAA-20 on the Thermal Emissive Bands

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2019
The Joint Polar Satellite System-1 (renamed NOAA-20 after reaching the polar orbit) was successfully launched on November 18, 2017, into an afternoon orbit with a local equator crossing time of ~1:30 p.m., in the same orbital plane as the Suomi National ...

Response of nutrients and primary production to high wind and upwelling-favorable wind in the Arctic Ocean: A modeling perspective

Frontiers in Marine Science, 2023
Both remote sensing and numerical models revealed increasing net primary production (NPP) in the Arctic Ocean due to declining sea ice cover and increasing ice-free days.

Changing NPP consumption patterns in the Holocene: From megafauna-'liberated NPP to 'ecological bankruptcy [PDF]

, 2016
There have been vast changes in how net primary production (NPP) has been consumed by humans and animals through the Holocene. Here we ask: how much NPP energy may have become available following the megafauna extinctions?

Impact Assessment of the M_s7.0 Earthquake on Jiuzhaigou Valley from the Perspective of Vegetation Net Primary Productivity

Sensors, 2022
In order to assess the impact of the Ms7.0 Jiuzhaigou earthquake that occurred on 8 August 2017 on vegetation, the Carnegie-Ames-Stanford Approach (CASA) model was adopted to estimate the vegetation net primary productivity (NPP) of Jiuzhaigou Valley ...
