The unprecedented size of the 2017 wildfires that burned nearly 600,000 hectares central Chile highlight a need to better understand climatic conditions under which large fires develop. Here we evaluate synoptic atmospheric at surface and free troposphere associated with anomalously high (active) versus low (inactive) months area in south-central (ca. 32–41° S) from Chilean Forest Service (CONA...

It is well known that some techniques have already been developed to automatically subdivide texts into multiparagraph subtopic passages, such as TextTiling methodology proposed by Hearst. However, an additional algorithm is needed to perform a similar task for parallel or variant texts, because ambiguous and complicated traces of cross citation among them might often generate some sinuous patt...

We report on the development and validation of a neural network (NN) model of PM10 concentrations in terms of photochemical measurements of NO, NO2 and O3 and temporal parameters that include the day of the week and the day of the year with its sinusoidal variation. A long-term record (≈10 yr) from 2001–2012 (inclusive) assembled from measurements taken at 10 station nodes in the air quality mo...
