Description: | Reprocessed ARM Raman Lidar water vapor data is available for the IHOP IOP period 20020515 to 20020625 at http://iop.archive.arm.gov/arm-iop/2002/sgp/ihop/turner-raman/ The data were reprocessed by Dave Turner to apply an improved near-field correction ("overlap correction") to the water vapor data collected by the Raman lidar during IHOP. These files contain only the water vapor data; users who require the aerosol and cloud fields from this instrument will need to retrieve the regular ARM data sets. |

Subject: | SGP/RL/C1 - Decreased sensitivity |
DataStreams: | sgp10rlprofmr1turnC1.c1 |
Description: | The sensitivity of the Raman Lidar degraded significantly beginning in late 2001. Between May and September 2004, the electronics were upgraded and the telescope was refurbished resulting in sensitivity better than when the instrument system was first installed. A detailed technical report describing the effects of the signal degradation and the steps taken to correct the problem is being written. In the interim, contact Dave Turner (dave.turner@pnl.gov) for more information. |
