Current spatial coverage of the satellite data available through the API.
Regions with the orange color are updated every few minutes (satellite based real-time and nowcasting data are available in the current day). In the yellow regions the satellite data is updated every day (so that DAY-1 is available, see below table for the exact timing). Main solar data parameters include GHI, DNI, DIF (the main calculated parameters are GTI and PVOUT). Map of satellite data regions.

| satellite data region | historical data start | description of satellites | local DAY-1 is available at | real-time and nowcasting availability |
| GOES WEST | 1999-01-01 | 2019+: GOES-S, 10-minute time step 2018 - 1999: GOES-W, 30-minute time step | 09:00 UTC | Satellite data availability delay is 2-12 minutes and it increases from south to north. Processing frequency is every 10 minutes and it takes another 5-15 minutes. |

Timestamps used in the XML response comply with the ISO 8601 standard for date and time representation https://en.wikipedia.org/wiki/ISO_8601. Time stamps are also aware of time zone (offset from UTC). Time zone designators are appended after the the time part of timestamp string. If the time is in UTC (https://en.wikipedia.org/wiki/Coordinated_Universal_Time), Z is added directly after the time without a space. Z is the zone designator for the zero UTC offset e.g., 2017-09-22T01:00:00.000Z . If there is an offset from UTC, this is designated by appending +/-HH:MM after the timestamp string, e.g., 2017-09-22T01:00:00.000-05:00 (UTC-5). |
