Normalized radar reflectivity factor data 2015-2019 from Ponte Nova weather radar (São Paulo – Brazil)
<|begin_of_text|><|start_header_id|>system<|end_header_id|> You are a research archivist expert in dataset metadata. Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'This dataset is from a dual-polarization S-band (SPOL) Doppler weather radar from the Department of Water and Electric Energy, operated by the Hydraulic Technology Center Foundation, installed at Ponta Nova, State of São Paulo, Brazil .The weather radar scans are Plan Position Indicators (PPIs) of horizontal reflectivity at 0.5o of elevation angle. The images are squares of approximately 140 km² with 4-km horizontal resolution (each image has 40 x 40 pixels). The dataset includes 87,500 scans from March 2015 to December 2019 with a time interval of 15 minutes. We scaled the original data from 0 to 60 dBZ into the [0, 1] interval, dividing by 60. Each PPI has been automatically quality controlled to avoid ground clutter and anomalous propagations by means of the coincident polari' . Please return only a json list of at most 3 Keywords corresponding to the Description:.<|eot_id|><|start_header_id|>assistant<|end_header_id|> {"Answer" : ["nowcasting","precipitation","radar","reflectivity","weather radar"]} <|eot_id|>
