  • Background

    The Earth Observing System (represented by Terra/Aqua/Aura) was intended toprovide global observations needed to advance Earth System Science and toinitiate a number of improved long- term global data sets.

    Suomi-NPP (launched in 2011) extends more than 11 high-quality TerrestrialEarth System Data Records (ESDRs) initiated by earlier NASA satellites.

    Cross comparison of the VIIRS and MODIS Aqua SRproducts for the BELMANIP2 sites (A). The plots show thatthe NASA reprocessing of VIIRS (C1.1) is in a goodagreement with MODIS (B). Continuous monitoring of VIIRSCollection V1 reprocessing ensures productstability/consistency.

    (C)

    Key Findings: VIIRS SR product secures the Long Term datacontinuity from the MODIS global Land record which iscrucial for the NASA Earth Science mission.

    Sea ice leads play a critical role in theexchange of mass and energy between theocean and atmosphere in the polar regions,particularly in the Arctic. We are developinga methodology to detect and characterizesea ice leads applied to MODIS and VIIRSdata to identify lead characteristics,including width, orientation, and spatialdistribution, which can aid in navigation andis essential to investigate any correlationswith observed chances in the Arctic Sea Ice.
