摘要

Artificial neural networks (ANNs) are very effective statistical models for (1) extracting significantnfeatures or characteristics from complex data structures and/or for (2) learning nonlinearnrelationships involved in any input–output mapping. Another interesting aspect of ANN modelingnis the fact that overall performance of these models is not greatly hampered by the presence ofnerror-corrupted values in some input nodes. ANNs have gained interest in remote sensingnapplications as valuable inverse models that can retrieve physical characteristics of interest, suchnas precipitation, from remote sensing measurements collected from radars or satellites. Thenspatial coverage and high resolution of remote sensing measurements relative to ground-basednmeasurements can improve the hydrological modeling of the water cycle at both local and globalnscales. This review paper intends to present recent advances in artificial neural network modelingnof remote sensing applications in hydrology. This paper focuses on precipitation and snow waternequivalent (SWE) retrievals from remote sensing data.
