abstract = "This paper discusses the basis for a new rainfall estimation
method using geostationary infrared and visible data. The
precipitation radar on board the Tropical Rainfall Measuring
Mission satellite is used to train the algorithm presented (which
is the basis of the estimation method) and the further
intercomparison. The algorithm uses daily Geostationary
Operational Environmental Satellite infrared-visible (IR-VIS)
cloud classifications together with radiative and evolution
properties of clouds over the life cycle of mesoscale convective
systems (MCSs) in different brightness temperature (T-b) ranges.
Despite recognition of the importance of the relationship between
the life cycle of MCSs and the rainfall rate they produce, this
relationship has not previously been quantified precisely. An
empirical relationship is found between the characteristics that
describe the MCSs' life cycle and the magnitude of rainfall rate
they produce. Numerous earlier studies focus on this subject using
cloud-patch or pixel-based techniques; this work combines the two
techniques. The algorithm performs reasonably well in the case of
convective systems and also for stratiform clouds, although it
tends to overestimate rainfall rates. Despite only using satellite
information to initialize the algorithm, satisfactory results were
obtained relative to the hydroestimator technique, which in
addition to the IR information uses extra satellite data such as
moisture and orographic corrections. This shows that the use of
IR-VIS cloud classification and MCS properties provides a robust
basis for creating a future estimation method incorporating
humidity Eta field outputs for a moisture correction, digital
elevation models combined with low-level moisture advection for an
orographic correction, and a nighttime cloud classification.",
