Description
GPM Ground Validation Physicum Building Mast Meteorological Data LPVEx V1 consists of meteorological measurements collected from the SMEAR III rooftop station at the University of Helsinki. The data, including temperature, pressure, wind, precipitation, and radiation, were gathered from September 16 to October 22, 2010, to support the Light Precipitation Validation Experiment (LPVEx) field campaign. This high-latitude ground truth dataset was created to improve precipitation retrieval algorithms for the Global Precipitation Measurement (GPM) mission satellites.
Use Cases
Validating satellite-based precipitation estimates based on ground-level meteorological measurements.
Analyzing light rainfall patterns in high-latitude coastal environments using precipitation and wind data.
Studying surface-atmosphere interactions using concurrent temperature, pressure, radiation, and humidity observations.
Calibrating remote sensing models for the GPM mission with in-situ data from a dedicated field campaign.
Strengths
Data originates from a recognized research station (SMEAR III) operated by the University of Helsinki.
Provides a precise temporal snapshot for a focused scientific campaign, covering September 16 to October 22, 2010.
Cross-platform presence on NASA and government data portals indicates established provenance and importance for the domain.
Limitations
Metadata completeness is low; column names and row counts are not provided in any source description.
Conflicting license information exists between sources ('other-license-specified' and 'None').
The dataset's temporal scope is limited to a 37-day period in 2010, restricting longitudinal analysis.
Provenance
Source
Station for Measuring Ecosystem-Atmosphere Relations III (SMEAR III), University of Helsinki, collected for NASA's GPM mission LPVEx campaign.
Collection Method
Ground-based measurements from a rooftop meteorological station.
