Light Pollution Raw Data

This service delivers data collected by a network of lightmeters (see also the service info).

Dates are given in as ranges of Julian Day numbers, e.g., 2455124 +/- 2 for two days around 2009-10-19 noon UTC, or 2455124.45 .. 2455124.55 for a centiday around midnight UTC 2009-10-19.

This service serves uncalibrated, high-resolution raw measurements as delivered by the orginal instruments. See Light Pollution Weather for a more accessible way to query this data, and use ADQL possibly via TAP, on the lightmeter.measurements table for more advanced queries.
