Resumo
Prediction models can be very useful when dealing with ciclic temporal sequence of data. For
ciclic sequences that have caotic behavior, like atmospherics measures, the Recurrent Neural Network(RNN) is
a potential option to create acurate prediction models.This type of neural network is effective in dealing with
temporal sequences because it uses its internal state as a memory to process certain data intervals.
In building the model, it is necessary to use layers with neurons to discern a trend that the data
sequence takes, for this, in the RNN model it is possible to use the long short-term memory (LSTM) architecture
to more easily predict unusual behaviors in the data stream, since its use facilitates the recognition of long-term
sequences in the analyzed sequence. This type of architecture can be added in layers to increase model
efficiency.
For the training and testing of the model, data obtained by the Metroclima project with a Cavity Ring
Down Spectroscopy (CRDS) at the UNICID station located in São Paulo were used, with the data ranging from
2019 to 2021. In this process, four LSTM layers will be used to create a prediction model that will be tested to
its limit on the effectiveness of predicting atmospheric data of this type.
