This paper provides a review and summary status of the research underway by NASA Terra Aqua Suomi-NPP Land Discipline Team to provide continuity global land data products from Moderate resolution Imaging Spectroradiometer (MODIS) Visible Infrared Radiometer Suite (VIIRS). The two MODIS instruments on Earth Observing System (morning overpass) (afternoon platforms have provided more than twenty years data. peer-reviewed generated are now being transitioned production using VIIRS inputs, with intention providing dynamic for observations. As part that process, undergoing intercomparison evaluation. These results where available show promising levels agreement accuracy in all cases. also offers options establishing products.

Global evaluation of Fengyun-3 MERSI dark target aerosol retrievals over land

International Journal of Digital Earth, Journal Year: 2024, Volume and Issue: 17(1), P. 1 - 24

Published: April 25, 2024

The Medium Resolution Spectral Image (MERSI) is a MODIS-like sensor aboard Fengyun-3 satellite. first version of MERSI aerosol algorithm has been developed based on MODIS dark target (DT) algorithm, with modified models for estimating surface reflectance and an adjusted inland water masking method to release haze aerosols. This study applies DT the global observations from upgraded (MERSI-II) Fengyun-3D. And then, Aerosol Optical Depth (AOD) results year 2019–2020 are validated against Robotic Network (AERONET) data. In addition, analyses spatial distribution error characteristics MERSI-II retrievals presented. overall validation demonstrates that perform well globally, correlation coefficient 0.877 67.1% matchups within Expected Error envelope ± (0.05 + 0.2τ), which close statistic metrics products. AODs exhibit similar trends dependence. Moreover, two revealed in retrieval performance at site regional scales, as analysis monthly averages. These findings indicate success ported algorithm.

Aerosol optical depth climatology from the high-resolution MAIAC product over Europe: differences between major European cities and their surrounding environments

Atmospheric chemistry and physics, Journal Year: 2023, Volume and Issue: 23(19), P. 12455 - 12475

Abstract. The aerosol optical depth (AOD) is a derived measurement useful to investigate the load and its distribution at different spatio-temporal scales. In this work we use long-term (2000–2021) MAIAC (Multi-Angle Implementation of Atmospheric Correction) retrievals with 1 km resolution climatological AOD variability trends scales in Europe: continental (30–60∘ N, 20∘ W–40∘ E), regional (100 × 100 km2) an urban–local scale (3 3 km2). climatology shows highest values during summer (JJA) lowest winter (DJF) seasons. Regional are investigated for 21 cities Europe, including capitals large urban agglomerations. Analyses show average (550 nm) between 0.06 0.16 while also displaying strong north–south gradient. This gradient corresponds similar one European background, higher being located over Po Valley, Mediterranean Basin eastern Europe. Average enhancements local respect 57 %, 55 39 % 32 found metropolitan centers such as Barcelona, Lisbon, Paris Athens, respectively, suggesting non-negligible enhancement burden through emissions. Negative deviations observed other cities, Amsterdam (−17 %) Brussels (−6 %), indicating background signal heterogeneous spatial that conceals signal. Finally, negative statistically significant entire continent observed. A stronger decrease rate occurs most under investigation.
