GES DISC - Big Data Archive

-- - ---· - ·-

O Archives total volume > 2.3 Petabytes consisting of > 110 million data files covering >2S00 public and restricted collections, distributes >23 Petabytes

o Multi-disciplinary data holdings include observations and model data of atmospheric composition, water /energy cycles, climate variability

o These include for example Aqua AIRS, Aura HIRDLS/MLS/OMI, TROPOMI, SORCE, TOMS, TOVS, TRMM/GPM, UARS, LDAS and M ERRNM ERRA-2.

o Through various available tools and services, the GES DISC provides users with multi-sensor and model visual comparisons and data access for a number of projects spanning several disciplines.

GES DISC Earth Observation (EO) Data Characteristics: Multi-spatiotemporal Datasets • Instrument type: Remote sensing, in-situ, modeling • Measurement Resolutions:

• Spatially: o Global grids (raster) with spatial resolution up to 4-km o Higher resolution swath (feature points) data (e.g., 2.2-km)

• Temporally: o Half-hourly, 3-hourly, daily, monthly satellite measurements o Hourly, 3-hourly, daily and monthly modeled products o Monthly ground observation archives o Composite Climatology (yearly, monthly) o Near-real-time (NRT) products

ArcGIS Challenges for Handling EO Data

1. Complex Data Format HDF, HDF-EOS, netCDF

2. Non-ArcGIS ready format swath data

3. Need additional analytics for long data records

Setting up ArcGIS Image Service for long term data record

• Long term data analysis through image service o GES DISC data usually contain long time data records, e.g., 40

years of hourly data o A single mosaic is not feasible for long time series o Hierarchical mosaics: daily, monthly, yearly, multi-year o Services can be set up at different hierarchical levels

• Top level service may be very slow to respond when first connected
