Data Access & Summary
View the EVE Data Access Page for documentation and descriptions.
| Level | Description | Wavelength Coverage | Data Link |
|---|---|---|---|
| 0CS | Space Weather: Crudely calibrated 1-minute averaged broadband irradiances from ESP and MEGS-P broadband photometers with minimum latency. | 0.1-7, 18.2, 25.6, 30.4, 36.6, and 121.6 nm | Latest day, Latest 15 minutes, Historical |
| 0C | Space Weather: Crudely calibrated 1-minute averaged spectral irradiance from MEGS with less than 15 minute latency. | 7-37 nm | Not yet available |
| 1 | Broadbands: Fully calibrated ESP photometer irradiances at instrument 4 Hz cadence. Full science potential, available next day. | 0.1-7, 18.2, 25.6, 30.4, 36.6 nm | Daily files |
| 2 – spectra | Spectrum: Fully calibrated merged spectra at 0.02 nm sampling and instrument 10 second cadence. Full science potential, available next day. Files start with “EVS_”. | 6.5-65 nm | Hourly files |
| 2 – lines | Lines, bands, diodes: 30 extracted emission lines, 20 extracted bands, and all photometer bands plus ESP quad diode fractions at the spectrum cadence of 10 seconds. Photometer data are averaged down to 10 seconds. Partial science potential, fulfills extracted line requirements, available next day. Files start with “EVL_” and reside in the same directories with the spectra. | Many | Hourly files |
| 3 | Daily Average: Daily averaged merged spectra at 0.02 nm sampling, extracted lines, bands, photometer data. Available next day. | 0.1-65 nm plus 121.6 nm | Daily files |
| 3 – merged | Mission-merged: Full mission of level 3 data in one file. Three different bin sizes available (0.02, 0.1, 1.0 nm). Available next day. | same as level 3 | Browse directory |
| 0C – SAM | Space Weather: SAM 5-minute irradiance peak and centroid locations. 4 minute latency. Currently in beta phase. An additional 1-minute file is being produced daily. | 0.1-7 nm | Latest 5-minute file, Browse 5-minute directory, Browse 1-minute directory |
Note that due to unexpected rapid degradation, MEGS-B (and consequently MEGS-P) have limited daily exposure. Solar measurements for MEGS-B are made 5 minutes each hour plus one 3-hour period each day.
