A single PDF record of weather measurements published by the national weather service, selected for one address and one date, delivered as a download immediately after payment. The price is €19 including any applicable VAT.

The record is a data extract. It is not an expert opinion, not a certificate, not a Gutachten and not legal advice. No assessment of damage, policy or claim is made or implied.

The free check shows the decisive measurement before any payment: the nearest station that measured, the distance, the peak gust and whether it reached the threshold quoted from standard conditions. If no station near the address holds data for that date, we say so and there is nothing to sell.

If the delivered record does not contain the measurements the free check showed, or the download fails and cannot be fixed, the payment is refunded in full on request within 30 days.

Because the record is a digital item generated on demand and delivered immediately, the statutory right of withdrawal for digital content ends once delivery has begun, which you agree to at checkout. The refund promise above applies regardless.

Figures are reproduced from the weather service's own archive without adjustment, apart from unit conversion and the selection of place and period. Values from the rolling recent archive are provisional and may be revised by the service; a record states which tier each figure came from and keeps the values as they stood when it was issued.

Payment is processed by lava.top, which acts as merchant of record and appears on your statement. Card details are never seen by this service.

The animated map exists to be understood, not to be relied on. The record is the PDF; the map is a picture of the same weather, drawn to show where the rain was and the moment it crossed the address.

Every frame of it is measured. The movement between frames is not. Between two measurements the rainfall field is computationally blended from one into the other, and carried along the direction the rain was measured to be moving, so that a storm reads as crossing a town rather than dissolving into another picture. In-between states are therefore interpolations between two measurements and not observations of their own; the figures on the timeline and in the report come exclusively from the measured frames.

Over Germany the map is drawn from the five-minute radar product. The figures in the record come from the hourly gauge-adjusted product and from named stations. These are different products with different adjustments, and their values differ by roughly a tenth. Neither is ever quoted as the other.

Outside Germany the map is a satellite estimate of about eight kilometres per cell in thirty-minute steps, with times in UTC, and it stops at sixty degrees north and south. It shows how much rain crossed an area. It is never the source of a figure in a record.
