Challenge: Earth live

Preventing the impact of natural disasters

Our planet is changing. We take care of It.

We develop a website that leverages NASA imagery and climate data to illustrate the impacts of our changing Earth apply to prevent the impact of natural disasters.

Our development

Natural disasters happen spontaneously. Their impact on air and water quality and on ecosystems can be quite aggressive. When a natural disaster occurs, air flows and/or sea water currents spread its impact into other geographical areas that can be many kilometers away. We plan to use a number of NASA satellites and instruments to measure the variations of the most important atmosphere molecules after natural disasters and model their influence to adjacent zones.


    Data from AIRS

    Launched aboard the NASA Earth Observing System satellite called "Aqua" in 2002, the Atmospheric Infrared Sounder (AIRS) instrument suite constitutes an innovative spaceborne atmospheric sounding system comprised of the AIRS hyperspectral infrared instrument and two multichannel microwave instruments the Advanced Microwave Sounding Unit (AMSU-A) and the Humidity Sounder for Brazil (HSB). Together these instruments observe global water and energy cycles, climate variation and trends, and the response of the climate system to increased greenhouse gases.

    AIRS retrieved data products provide a daily global view of the three-dimensional physical state of the atmosphere (air temperature, water vapor, clouds) and the distribution of trace gas constituents (ozone, carbon monoxide, carbon dioxide and methane).

    The AIRS instrument on NASA's Aqua satellite orbits Earth from pole-to-pole, fifteen times each day. The same area on Earth is covered two times per day, in a descending orbital pass which occurs at 1:30 am local time, and an ascending orbital pass at 1:30 pm local time. As the instrument moves along, it scans from side to side, creating a swath in which data is collected. At the north pole the swaths overlap but at the equator gaps occur between swaths. These gaps are eventually scanned within two to three days.

    We extract the data from publications:
    AIRS Science Team/Joao Texeira (2010), AIRS/Aqua Level 2 CO2 in the free troposphere (AIRS+AMSU), version 005, Greenbelt, MD, USA, Goddard Earth Science Data and Information Services Center (GES DISC), Accessed at 10.5067/AQUA/AIRS/DATA218
    AIRS Science Team/Joao Texeira (2009), AIRS/Aqua Level 3 Daily CO2 in the free troposphere (AIRS-only), version 005, Greenbelt, MD, USA, Goddard Earth Science Data and Information Services Center (GES DISC), Accessed at 10.5067/AQUA/AIRS/DATA335

    Problems located

    The greatest problem to reach our target it is data acquisition, the data dispersion while collecting data, a lot of different data structure and formats, and a lack of consistency and huge deficiency in the API to retrieve all data wanted.

    We realized the real need of a software that could seed all data necesary to anybody who needs it in a simplest way.
