4 of August of 1999 - Image NOAA 14, Composition RGB 3.2.1 1,100km of resolution per pixel Zone: Province of Corrientes, Argentina.

Due to the importance that the phenomenon object of this image has, we decided to include this as an example of fire detection, although the mentioned phenomenon happened outside the limits of our country. In this composition we can observe clearly a series of small red-orange points, some of which are associate with bluish shapes that look "simila" to comets. The great sensibildad that band 3 of the satellites of the NOAA series has, in which refers to the detection of high temperatures (very over the average of normal thermal emission of our planet), added to the capacity of band 1 in the referring thing to emphasizes of all type of cloudiness, allows us to affirm that we are without doubt in the presence of fires. The red-orange points correspond to the fire centers, whereas the formation bluish is not another thing that the feathers of smoke generated by such (look that these feathers follow a pattern determined by predominates winds in that region at the time of being captured the image). As it can also be appraised, numerous points of that same color exist that don't be associated whit any smoke feather. In that case, we can`t affirm categorically that they correspond to fires. Specular effects and simple "signal noise" in the caption of the image can take to us to commit interpretation errors. What it's suggested in these cases, is to collate the diurnal image later (like which we see in the example) with a nocturnal image received some hours after: although the solar absence of light will have to us to prevent to visualize smoke feathers, the persistence or not of high temperatures in those zones that present doubts about their state (band 3), it will have to confirm to us if there are fires. The date in which this image was caught (4/8/1999) and the dispersion of the centers, induces to us to think that these fires are of intentional origin and have as object controlled weeds burns. However, this same vision during a warm and dry summer, could be foretelling a terrible natural catastrophe.
