Un vero motore di previsione, non un proxy

SkiesAtlas non si limita a inoltrare dati di terzi. Acquisiamo l'output grezzo dei modelli numerici, lo decodifichiamo, scegliamo il modello migliore per ogni coordinata e lo unifichiamo in un'API pulita e coerente, servita in meno di 200 ms.

1 · Acquisizione

Preleviamo l'output GRIB grezzo direttamente dai principali centri meteo mondiali, a ogni esecuzione del modello.

2 · Instradamento

Per ogni coordinata selezioniamo il modello a più alta risoluzione disponibile: ICON-D2 2 km, HRRR 3 km o ECMWF 9 km ovunque. Automatico e trasparente.

3 · Unificazione

Sei formati di modello diversi diventano un unico schema JSON prevedibile: gli stessi nomi di campo ovunque, unità metriche e timestamp ISO.

4 · Distribuzione

Una cache aggressiva per esecuzione fornisce risposte in meno di 200 ms, con fallback automatico agli ultimi dati affinché la tua app non resti mai al buio.

Fonti di dati e licenze

Dietro le quinte decodifichiamo e combiniamo questi modelli meteo e oceanici ufficiali, con licenza aperta, in un'unica API.

Precisione di cui fidarsi

Ci basiamo sulla migliore scienza disponibile e ci verifichiamo costantemente.

Modelli di primo livello

ECMWF IFS è costantemente considerato il modello globale più preciso al mondo. Lo usiamo come base mondiale e vi sovrapponiamo modelli regionali ad alta risoluzione.

Validato di continuo

Ogni poche ore confrontiamo i nostri risultati con previsioni di riferimento indipendenti su oltre 20 città nel mondo per individuare tempestivamente ogni deriva.

Aggiornato tutto il giorno

I modelli si aggiornano fino a quattro volte al giorno (00/06/12/18 UTC). Il nostro motore riacquisisce ogni esecuzione automaticamente, così hai sempre la previsione più recente.

Live forecast accuracy

● verified continuously

Mean absolute temperature error (°C) vs real METAR observations at 1130 global stations — lower is better. Our backbone ECMWF-AIFS and the multi-model BLEND lead the field.

Model	analysis	+24h	+48h	+72h	+120h
ICON-EU	1.03	1.15	1.25	1.37	1.55
ECMWF-AIFS backbone	1.25	1.34	1.40	1.47	1.54
BLEND	1.32	1.45	1.54	1.62	1.76

Full scores (all parameters, lead times & regions) via GET /api/v1/accuracy. Longer lead-time skill fills in as forecast/observation pairs accumulate.

Autenticazione & Limiti di richieste

Autenticazione

Trasmetti la tua chiave API nell'header X-API-Key (consigliato) o come parametro api_key.

# Header (recommended)
curl -H "X-API-Key: YOUR_KEY" "https://skiesatlas.com/api/v1/weather?lat=48.85&lon=2.35"

# Query parameter
curl "https://skiesatlas.com/api/v1/weather?lat=48.85&lon=2.35&api_key=YOUR_KEY"

Limiti di richieste

Ogni risposta indica il tuo utilizzo negli header. Superare la quota restituisce 429 Too Many Requests: attendi prima di riprovare.

Header	Description
`X-RateLimit-Limit`	Your daily request limit (paid plans).
`X-RateLimit-Remaining`	Requests left today.

Plan	Quota	HTTP on exceed
Free	500 requests / day	`429`
Basic	10,000 requests / day	`429`
Starter	50,000 requests / day	`429`
Pro	200,000 requests / day	`429`
Business	1,000,000 requests / day	`429`

Quotas reset every day at 00:00 UTC, on the free plan too. A 402 is different: it means the endpoint itself requires a higher plan (/nowcast needs Starter or above; /batch, /history, /radar, /lightning, /probabilities, /alerts and /route need Pro or above).

Domande frequenti

Da dove vengono i dati meteo?

Facciamo girare un nostro motore sopra i migliori modelli aperti al mondo: ECMWF IFS, DWD ICON, NOAA GFS/HRRR, WaveWatch III, Copernicus CAMS e MUR SST. Decodifichiamo l'output grezzo, instradiamo ogni richiesta al modello a più alta risoluzione per quella località e restituiamo un'unica risposta pulita e coerente. Ottieni un prodotto vero, non sei flussi grezzi da assemblare da solo.

Quanto sono precise le previsioni?

Usiamo ECMWF IFS — considerato il modello globale più preciso al mondo — come base, più modelli regionali ad alta risoluzione (2–3 km) dove disponibili. Validiamo di continuo rispetto a riferimenti indipendenti, con uno scarto tipico di circa 0,6 °C sulla temperatura.

Quali sono i limiti di richieste?

Ogni piano ha una quota giornaliera che si azzera alle 00:00 UTC — piano gratuito incluso: 500 richieste al giorno, rinnovate ogni giorno. Piani a pagamento: Basic 10.000/giorno, Starter 50.000/giorno, Pro 200.000/giorno, Business 1.000.000/giorno. Ogni risposta indica la quota residua nell'intestazione X-RateLimit-Remaining.

Posso annullare in qualsiasi momento?

Sì. Gli abbonamenti sono mensili e puoi annullare in qualsiasi momento: il tuo piano resta attivo fino alla fine del periodo pagato, poi torna automaticamente a gratuito.

Posso usarla con gli agenti IA?

Certamente. SkiesAtlas offre un server MCP nativo su https://skiesatlas.com/mcp — aggiungilo a Claude Desktop, Cursor o a qualsiasi client MCP e il tuo agente ottiene strumenti meteo in tempo reale.

Fornite le maree?

Sì, tramite l'endpoint /api/v1/tides, alimentato da TidesAtlas — orari e altezze di marea per oltre 17.000 porti nel mondo.
