S5P_L2_FRESCO
Variables
The table below lists the variables that are present in the HARP product that results from an ingestion of S5P_L2_FRESCO data.
| field name | type | dimensions | unit | description |
|---|---|---|---|---|
| index | int32 | {time} | zero-based index of the sample within the source product | |
| scanline_pixel_index | int16 | {time} | pixel index (0-based) within the scanline | |
| datetime | double | {time} | seconds since 2000-01-01 | start time of the measurement |
| longitude | float | {time} | degree_east | longitude of the ground pixel center (WGS84) |
| latitude | float | {time} | degree_north | latitude of the ground pixel center (WGS84) |
| cloud_fraction | float | {time} | effective cloud fraction | |
| cloud_fraction_stdev | float | {time} | effective cloud fraction precision (1 sigma error) | |
| cloud_pressure | float | {time} | hPa | cloud pressure, at approximately the mid-level of the cloud layer |
| cloud_pressure_stdev | float | {time} | hPa | cloud pressure precision (1 sigma error) |
| cloud_height | float | {time} | m | cloud height, at the optical centroid level, measured from the surface |
| cloud_height_stdev | float | {time} | m | cloud height precision (1 sigma error) |
| cloud_albedo | float | {time} | cloud albedo; this is a fixed value for FRESCO | |
| cloud_albedo_stdev | float | {time} | cloud albedo error; since cloud albedo is fixed for FRESCO, this value is set to NaN | |
| scene_albedo | float | {time} | scene albedo when FRESCO is running in snow/ice mode (this quantity is required by the CH4 processor) | |
| scene_albedo_stdev | float | {time} | scene albedo precision (1 sigma error) when FRESCO is running in snow/ice mode | |
| scene_pressure | float | {time} | hPa | apparent scene pressure when FRESCO is running in snow/ice mode (this quantity is required by the CH4 processor) |
| scene_pressure_stdev | float | {time} | hPa | apparent scene precision (1 sigma error) when FRESCO is running in snow/ice mode |
