EOSDIS New Datasets: May 2017

Earth Observing 1 (EO-1)

Satellite imagery data products from two sensors onboard NASA's EO-1 satellite are now available through NASA’s Earthdata Search. Direct download of the data leverages the USGS EarthExplorer, which requires login credentials ( https://ers.cr.usgs.gov/register/). The EO-1 products that are available consist of data collected beginning in May 2001 through March 2017. Data collected by the EO-1 Advanced Land Imager (ALI) are comparable to Landsat panchromatic and multispectral bands at 10 meter and 30 meter resolutions, respectively. The EO-1 Hyperion hyperspectral imager provides 220 unique spectral bands at 30 meter resolution. These data support a wide range of applications such as mining, geology, forestry, agriculture and environmental management.

GES DISC

NASA's Goddard Earth Sciences Data and Information Services Center (GES DISC) released Version 2 Level-1B (L1B) data products from the Ozone Mapping and Profiler Suite (OMPS) Nadir Mapper (NM) and Nadir Profiler (NP) instruments on the joint NASA/NOAA Suomi National Polar-orbiting Partnership (Suomi NPP) satellite:

  • OMPS/Suomi NPP L1B NM Earth View (EV) Calibrated Geolocated Swath Orbital V2 (OMPS-NPP_NMEV_L1B)
  • OMPS/Suomi NPP L1B NP Earth View (EV) Calibrated Geolocated Swath Orbital V2 (OMPS-NPP_NPEV_L1B)

GHRC DAAC

NASA's Global Hydrometeorology Resource Center Distributed Active Archive Center (GHRC DAAC) has published an update to the LIS/OTD Gridded Lightning Climatology Data Collection to incorporate Lightning Imaging Sensor (LIS) data from the last year of data from Tropical Rainfall Measuring Mission (TRMM). This collection comprises the ten LIS/OTD Gridded Lightning Climatology Datasets listed below. These ten datasets offer full, annual, monthly and diurnal climatologies of lightning observed from space from May 1995 through December 2014, including both Optical Transient Detector and TRMM Lightning Imaging Sensor, at 0.5 and 2.5 degree resolutions. The three time series datasets also include data for January through April 2015. All data are available in both netCDF and HDF formats.

GHRC DAAC has also published two Ground Validation datasets for NASA's Global Precipitation Measurement (GPM) mission:
  • Dual-frequency Dual-polarized Doppler Radar (D3R) Olympic Mountain Experiment (OLYMPEX)
  • The OLYMPEX D3R dataset contains radar reflectivity and doppler velocity measurements. The D3R was developed by a government-industry-academic consortium with funding from NASA’s Global Precipitation Measurement (GPM) Project and was used in several ground validation projects. D3R operates at the Ku band (13.91 GHz ± 25 MHz) and Ka band (35.56 GHz ± 25 MHz) frequencies, like those on GPM satellite instruments, covering a fixed range from 450 m to 40 km. For OLYMPEX, the D3R was collocated with the NASA S-Band Dual-Polarimetric Radar (NPOL) radar at a coastal Washington state location on the Olympic Peninsula. Due to blockage caused by NPOL, the measurement sector is limited to a 220 deg to 120 deg sector. The data is available in netCDF format.
  • TRMM Multi-satellite Precipitation Analysis (TMPA) IPHEx
  • The Integrated Precipitation and Hydrology Experiment (IPHEx) TRMM Multi-satellite Precipitation Analysis (TMPA) a subset of the TMPA 3B42RT gridded precipitation product selected for the time period of the GPM Ground Validation (GPM-GV) IPHEx held in North Carolina during May 1, 2014 to June 15, 2014. The goal of IPHEx was to characterize warm season orographic precipitation regimes and the relationship between precipitation regimes and hydrologic processes in regions of complex terrain. This dataset contains 3-hourly, 0.25 degree maps of precipitation derived using microwave (MW), infrared (IR), surface precipitation gauge measurements, and other rain products that include the TRMM Precipitation Radar (PR) data. The IPHEx TMPA product is available in netCDF-4 and binary formats.

GHRC DAAC has published the Global Precipitation Measurement Ground Validation (GPM-GV) High Altitude Imaging Wind and Rain Airborne Profiler (HIWRAP) Olympic Mountain Experiment (OLYMPEX). OLYMPEX was the final GPM mission Ground Validation field campaign. HIWRAP is a Doppler radar designed to measure tropospheric winds through deriving Doppler profiles from cloud and precipitation volume backscatter. (Li et al. 2016). The winds are generated by combining conical scan mode measurements at two different frequency bands (Ka- and Ku-band) and two different incidence angles (30 and 40 degrees). HIWRAP utilizes solid state transmitters along with a novel pulse compression scheme resulting in a system that is considerably more compact and requires less power than typical radars used for precipitation and wind measurements. A more detailed description of the HIWRAP system and system parameters can be found in Li et al., 2016. More information about the HIWRAP instrument can be found at NASA's Goddard Space Flight Center High Altitude Radar Group.

NSIDC DAAC

NASA's National Snow and Ice Data Center DAAC (NSIDC DAAC) reported that Making Earth Science Data Records for Use in Research Environments (MEaSUREs) has added SSM/I data from the F11 platform to the MEaSUREs Calibrated Enhanced-Resolution Passive Microwave Daily EASE-Grid 2.0 Brightness Temperature ESDR dataset available at NSIDC DAAC. The temporal coverage is now 9 July 1987 through 4 October 2011.

The MEaSUREs Greenland Ice Velocity: Selected Glacier Site Velocity Maps from interferometric synthetic aperture radar (InSAR), Version 2 dataset is now available at NSIDC DAAC. This dataset consists of mean monthly velocity maps for selected glacier outlet areas. The maps are generated by tracking visible features between optical image pairs acquired by the Landsat 7 Enhanced Thematic Mapper Plus (ETM+), the Landsat 8 Operational Land Imager (OLI), and the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER). The Version 2 update expands the temporal coverage of the dataset through September 2016, using cross-path Landsat pairs to fill in temporal gaps in the 2016 data. Version 2 also includes the application of a more aggressive filtering method, the correction of misnamed error values, and the addition of a west coast grid at 80.75 degrees north.

ORNL DAAC

The Moderate Resolution Imaging Spectroradiometer (MODIS) collection 6 Albedo products have been added to NASA's Oak Ridge National Laboratory DAAC (ORNL DAAC) MODIS Global subsets and visualization tool. The albedo products utilize

  • LP DAAC backend for subsetting
  • Expands the backend of the global tool to provide daily products
  • Expands the ORNL DAAC MODIS subsetting capability for post-processing utilizing LP DAAC subsets.

PO.DAAC

NASA's Physical Oceanography DAAC (PO.DAAC) announced that they successfully ingested and made available a new Gravity Recovery and Climate Experiment (GRACE) accelerometer dataset named “SuperSTAR Accelerometer (ACC1B) R3 Transplant Data” from the GRACE Project. This dataset consists of accelerometer data synthesized for the GRACE-B satellite, beginning November 2016. This allows the expert user to recover gravity fields for the GRACE mission in the same manner as when both GRACE accelerometers were operational, with some added noise. This method is now used by the project to generate the GRACE Level 2 monthly gravity solutions since November 2016.

Operational data ingestion has begun at PO.DAAC for the Cyclone Global Navigation Satellite System (CYGNSS) Project. The first datasets being ingested are the CYGNSS Level 0A Raw Telemetry Data Record and Level 0B Packetized and Time-Ordered Telemetry Data Record Version 1.0.

The initial set of provisional Level 1, Level 2, and Level 3 Version 1.0 Science Data Record datasets, received from the Cyclone Global Navigation Satellite System (CYGNSS) Project remote provider site at the University of Michigan, have been fully ingested and are available on NASA's Physical Oceanography DAAC (PO.DAAC) website.

SEDAC

NASA's Socioeconomic Data and Applications Center (SEDAC) released a beta version of the Global 3-Year Running Mean Ground-Level NO2 Grids from Global Ozone Monitoring Experiment (GOME), Scanning Imaging Absorption Spectrometer for Atmospheric ChartographY (SCIAMACHY), and GOME-2 dataset on 28 April (see: http://beta.sedac.ciesin.columbia.edu/data/set/sdei-global-3-year-running-mean-no2-gome-sciamachy-gome2). The dataset consists of a series of three-year running mean grids from 1996 to 2012 of ground level nitrogen dioxide (NO2) derived from data from three instruments: GOME, SCIAMACHY and GOME-2.
