-=== Atmospheric Composition ===+  * AI for extreme extreme weather events and climate services (ASTERISKS H2020). Deep Neural Networks from the field of computer Vision can be used for pattern recognition in a supervised way, exploiting reanalysis data and historical event databases (e.g., IBTrACS for tropical cyclones) or other impact data.  
 +   
 +  * Learning to simulate precipitation with Deep Neural Networks ({{https://www.esiwace.eu/events/6th-hpc-workshop/presentations/learning-to-simulate-precipitation-with-deep-neural-networks|slides}}). Talk presented at the 6th ENES HPC workshop. We implemented encoder-decoder networks, such as those used for image translation in Computer Vision, for the task of learning precipitation fields from other predictor variables. The  transfer function aims to capture information from predictor variables to infer precipitation, a variable highly dependent on parameterizations schemes. 
  
-Currently working on the application of classification methods +  * Simulating precipitation with supervised and generative learning models. Abstract submitted to the ECMWF-ESA Workshop on Machine Learning for Earth System Observation and Prediction. We compare data-driven models based on supervised convolutional neural networks and conditional generative adversarial networks for simulating precipitation fields.

-on the concentration of specific pollutantsAnother topic of study is the improvement +  * May Deep Learning contribute to improve Downscaling techniques? ({{:library:external:pen_a-izquierdo_downscalingwithdl_isms2020.pdf |poster}}). Presented at the ISMSM 2020 conferenceWe implemented encoder-decoder networks for the task of downscaling, that is taking climate variables from a low resolution simulation (predictorsfor training an deep neural network to produce an observational gridded field at higher spatial resolution.
