Questa pagina contiene i dati degli 8 radiosondaggi italiani attivi, con dati ottenuti due volte al giorno alle ore sinottiche principali (00z e 12z).
Nella pagina principale troviamo i dati di pressione/altezza geopotenziale/temperatura per alcune superfici isobariche, nonchè i grafici Skew T-ln P e l’Odografo; per visualizzare i dati completi per ciascun radiosondaggio basta selezionare l’apposito pulsante o il link in alto.
I dati completi sono i seguenti: pressione, altezza geopotenziale, temperatura, dew-point (punto di rugiada), umidità, mixing-ratio, direzione e velocità del vento, temperatura potenziale, temperatura potenziale equivalente e temperatura potenziale virtuale.
Vi è inoltre una tabella contenente tutti gli indici termodinamici, nonchè i grafici Skew T-ln P, ricavati e calcolati dai dati registrati dal pallone-sonda (per l’interpretazione dei dati si rimanda all’articolo di approfondimento in basso).
Infine è presente l’archivio storico completo di tutti i radiosondaggi, comprese le stazioni dismesse (dati dell’Università di Wyoming).
