- Abstract
- The
NASA/JAXA Global Precipitation Measurement (GPM) mission
has launched its core satellite at the
end of February 2014. Along the mission, International science collaboration in the GPM
Ground Validation (GV) program is expected to play
a vital role in refining remote sensing algorithms and in assessing
both the quality and utility of satellite precipitation products
in different climate and geographic regimes.
The GPM GV program aims at using in an optimal way
a set of ground-based instrumentation, such research and operational
weather radars and raingauge networks. The \"Tier-1\" identifies research
radars that are operated by research institutions that have
a full control of the system to define measurement strategy that
can be optimized for direct validation in correspondence of GPM core satellite
overpasses. Typically, these radars belong to different organizations and
have been developed with different approaches
and for different objectives.
Some of them features unique and distinctive technical
characteristics. To ensure consistency of comparisons
with the single reference of the instruments
of GPM core satellite, guidelines have been
set both to ensure calibration and to use scanning
strategies in correspondence of core satellite overpasses
to allow intercomparison of data. In fact, these radars have
to provide on a regular basis a reference for GPM core
satellite overpasses and radar data they provide should
be comparable each other and provide a consistent reference across the
globe for satellite estimates. Weather radars typically use
a narrow beam and achieve a description of precipitation volume
by scanning it. From the point of view
of scanning, radars differs for mechanical characteristics
and/or mechanical limitations.. his paper illustrates criteria
used to define a set of scanning modes
and protocols that can be followed
so that all the radar observations
of the diverse Tier-1 radars
contributing to the global GPM GV effort, can meet a common
acceptable standard to be comparable. (literal)
