  • Aqua AIRS-MLS Matchup Indexes V1.0 (AIRS_MLS_IND) at GES_DISC

    https://cmr.earthdata.nasa.gov/search/concepts/C1451934338-GES_DISC.xml
    Description:

    This dataset is part of MEaSUREs 2012 Program, and represent Aqua/AIRS-Aura/MLS collocation indexes, in netCDF-4 format. These data map AIRS profile indexes to those of MLS. The A-Train provides water vapor (H2O) retrievals from both the Atmospheric Infrared Sounder (AIRS) and Microwave Limb Sounder (MLS). While AIRS loses sensitivity to H2O at the elevated portions of the upper troposphere (UT), MLS cannot detect H2O below 316 hPa. Therefore, to obtain a full profile of H2O in the whole column of air, this dataset manages to join the two products together by utilizing their own averaging kernels (AK). In doing so, the dataset builds a solid H2O of the whole column of air, which will help understand the H2O budget and many processes governing the humidity around the upper troposphere and lower stratosphere (UTLS). The short name for this collections is AIRS_MLS_IND

  • ARCTAS Supplementary Satellite Data Products

    https://cmr.earthdata.nasa.gov/search/concepts/C2449529636-LARC_ASDC.xml
    Description:

    ARCTAS_Satellite_Data is the supplementary satellite data for the Arctic Research of the Composition of the Troposphere from Aircraft & Satellites sub-orbital campaign. Data from TES, MOPITT and OMI are featured in this data product and data collection is complete. The Arctic is a critical region in understanding climate change. The responses of the Arctic to environmental perturbations such as warming, pollution, and emissions from forest fires in boreal Eurasia and North America include key processes such as the melting of ice sheets and permafrost, a decrease in snow albedo, and the deposition of halogen radical chemistry from sea salt aerosols to ice. Arctic Research of the Composition of the Troposphere from Aircraft and Satellites (ARCTAS) was a field campaign that explored environmental processes related to the high degree of climate sensitivity in the Arctic. ARCTAS was part of NASA’s contribution to the International Global Atmospheric Chemistry (IGAC) Polar Study using Aircraft, Remote Sensing, Surface Measurements, and Models of Climate, Chemistry, Aerosols, and Transport (POLARCAT) Experiment for the International Polar Year 2007-2008. ARCTAS had four primary objectives. The first was to understand long-range transport of pollution to the Arctic. Pollution brought to the Arctic from northern mid-latitude continents has environmental consequences, such as modifying regional and global climate and affecting the ozone budget. Prior to ARCTAS, these pathways remained largely uncertain. The second objective was to understand the atmospheric composition and climate implications of boreal forest fires; the smoke emissions from which act as an atmospheric perturbation to the Arctic by impacting the radiation budget and cloud processes and contributing to the production of tropospheric ozone. The third objective was to understand aerosol radiative forcing from climate perturbations, as the Arctic is an important place for understanding radiative forcing due to the rapid pace of climate change in the region and its unique radiative environment. The fourth objective of ARCTAS was to understand chemical processes with a focus on ozone, aerosols, mercury, and halogens. Additionally, ARCTAS sought to develop capabilities for incorporating data from aircraft and satellites related to pollution and related environmental perturbations in the Arctic into earth science models, expanding the potential for those models to predict future environmental change. ARCTAS consisted of two, three-week aircraft deployments conducted in April and July 2008. The spring deployment sought to explore arctic haze, stratosphere-troposphere exchange, and sunrise photochemistry. April was chosen for the deployment phase due to historically being the peak in the seasonal accumulation of pollution from northern mid-latitude continents in the Arctic. The summer deployment sought to understand boreal forest fires at their most active seasonal phase in addition to stratosphere-troposphere exchange and summertime photochemistry. During ARCTAS, three NASA aircrafts, the DC-8, P-3B, and BE-200, conducted measurements and were equipped with suites of in-situ and remote sensing instrumentation. Airborne data was used in conjunction with satellite observations from AURA, AQUA, CloudSat, PARASOL, CALIPSO, and MISR. The ASDC houses ARCTAS aircraft data, along with data related to MISR, a satellite instrument aboard the Terra satellite which provides measurements that provide information about the Earth’s environment and climate.

  • ATom: Column-Integrated Densities of Hydroxyl and Formaldehyde in Remote Troposphere

    https://cmr.earthdata.nasa.gov/search/concepts/C1592243446-ORNL_DAAC.xml
    Description:

    This dataset provides profile-integrated column densities of formaldehyde (HCHO), hydroxyl (OH), and OH production rates, diel tropospheric mean OH concentrations, and uncertainties that were derived from direct observation data from selected profiles of NASA Atmospheric Tomography (ATom) mission 1 and 2 flights for the period July 29, 2016 to February 21, 2017. These calculated products were combined with coincident HCHO column retrievals from the Ozone Monitoring Instrument (OMI) to scale and extend the profile results to a global gridded (0.5 deg latitude x 0.625 deg longitude) product. In addition to OMI formaldehyde column data, model output products from the Global Modeling Initiative (GMI) including average tropopause height, scaling factor, column air mass, and column-average formaldehyde photolysis frequency are provided. The GMI model output products were used in calculations and are included for user convenience.

  • Cemar Routine Monitoring of Macroalgal and Phytoplankton Diversity

    https://cmr.earthdata.nasa.gov/search/concepts/C1214586135-SCIOPS.xml
    Description:

    We have identified three locations with an exposed and a sheltered site each. To monitor each site we have devised a system of transect based stratified sampling (based on the natural zonation of the coastal habitat) to estimate percent cover of algal species on the beach (useful for a variety of standard statistical procedures). We are also compiling 'complete' species inventories during our trips so that we can apply a new type of analyses, Taxonomic Distinctness, which will allow us to compare our contemporary data to historical records for the region. Our intention is to maintain this program over a few decades. This project will, if supported in the long term, provide a valuable data set for understanding floristics in this important and unique region. NSERC's recent reallocation has highlighted the critical shortage of taxonomic experts capable of identifying the organisms that constitute Canada's biodiversity. The value of biodiversity to society is lost if the know-how to survey, identify, protect and access available species does not exist. Furthermore, long-term monitoring is essential if we are going to set a baseline for future comparisons and distinguish natural patterns of species fluctuations versus perturbations caused by human impact. Our routine monitoring of algal biodiversity in the Bay of Fundy is designed to address all of the previous issues. Type: Bay Waterbody or Watershed Names: Bay of Fundy
