Subject: | SGP/MWR/C1 - calibration checks |
DataStreams: | sgpmwrlosC1.a1, sgpmwrlosC1.b1, sgpmwrtipC1.a1 |
Description: | The MWR calibration was checked by a cryogenic (liquid nitrogen) blackbody target or (in the case of the Sept 2001 time period) by pointing the mirror at an internal blackbody target. The brightness temperatures and vap and liq retrievals are not representative of the sky/atmosphere. |

Description: | On 9/18/00, I found that the time on the MWR laptop was 1m 21s slow. The Dimension4 utility had last synchronized the time on 5/5/00. Found that the network DNS settings had been disabled. Added the DNS entry for ntp host CF10. Dimension4 synchronized the clock by adding 80.91s. The time had drifted at a rate of -0.59s/day. |

Subject: | SGP/MWR/C1 - Reprocess: IRT insufficiently insulated |
DataStreams: | sgpmwrlosC1.a1, sgpmwrlosC1.b1 |
Description: | The downwelling IRT was insufficiently insulated to maintain an internal reference temperature above 0 degrees C. Measurements of sky temperature were over-estimated when instrument was below freezing. Data will be reprocessed, but users can correct data using the following correction factor: If T_reference < -5?C, then IRT_corrected = (IRT_original - 32.993K)/0.87238 where T_reference can be estimated with the ambient temperature (e.g. tkair) |

DataStreams: | sgp1mwravgC1.c1, sgp5mwravgC1.c1, sgpmwrlosC1.a1, sgpmwrlosC1.b1 |
Description: | Several related and recurring problems with the SGP MWRs have been reported dating back to 1999. These problems were due to the occurrence of blackbody signals (in counts) that were half of those expected. The symptoms included noisy data (especially at Purcell), spikes in the data (especially at Vici), negative brightness temperatures, and apparent loss of serial communication between the computer and the radiometer, which results in a self-termination of the MWR program (especially at the CF). Because these all initially appeared to be hardware-related problems, the instrument mentor and SGP site operations personnel (1) repeatedly cleaned and replaced the fiber optic comm. components, (2) swapped radiometers, (3) sent radiometers back to Radiometrics for evaluation (which has not revealed any instrument problems), and (4) reconfigured the computer's operating system. Despite several attempts to isolate and correct it, the problem persisted. It became apparent that some component of the Windows98 configuration conflicted with the DOS-based MWR program or affected the serial port or the contents of the serial port buffer. This problem was finally corrected by upgrading the MWR software with a new Windows-compatible program. |

Subject: | SGP/MWR/C1 - Wet window flag "on" more frequently than expected |
DataStreams: | sgpmwrlosC1.a1, sgpmwrlosC1.b1 |
Description: | The wet window flag was set "on" more frequently than expected during the time periods specified. This indicates the heater has been running more than necessary. In most instances the moisture sensitivity was adjusted at the end of these periods. |

This is outside of the specified uncertainty in the IRT and indicates that the calibration needs to be revised. |

Subject: | SGP/MWR/C1 - IRT lens replaced |
DataStreams: | sgpmwrlosC1.a1, sgpmwrlosC1.b1 |
Description: | During my recent trip to the SGP I noticed that the IRT was reading too high (about 250 K for clear sky with less than 2 cm PWV). The anti-reflective coating on the lens appeared to have deteriorated significantly. Because I observed no change in the measurements after cleaning the lens, I replaced it with the original lens which had been saved as a spare. The measured sky temperature fell to 232 K, which appeared more reasonable. The next morning I realized that I had forgotten to clean the lens after replacing it. After cleaning the IR temperature fell from 219 to 213 K with about 1.2 cm PWV. This appeared to be in agreement with Martin Platt's radiometer which measures the same passband (10 micrometers.) Upon returning to Ames, I compared the IRT with AERI for April 1998. It appears that at least as far back as 1 April the IRT data are bad. |

Subject: | SGP/MWR/C1 - Erroneous internal temperature |
DataStreams: | sgpmwrlosC1.a1, sgpmwrlosC1.b1, sgpmwrtipC1.a1 |
Description: | After the new internal temperature sensor was installed it was discovered that the scaling resistor was incorrect. (The 24.9 kohm 0.1% resistor had accidently been replaced with a 24.0 kohm resistor when the analog board was repaired by the manufacturer several years ago.) A resistor having the correct value was installed 981112. |

Description: | The MWR operating software was changed on 12 October 1998 to provide additional functionality as described below. This change affects the format of the raw and ingested data. NEW FEATURES 1. Faster sampling rate Standard line-of-sight (LOS) observations can now be acquired at 15-second intervals vs. 20-second intervals previously. (The standard LOS cycle is comprised of one sky sample per blackbody sample and gain update.) 2. More flexible sampling strategy Multiple sky observations can be acquired during a LOS cycle, up to 1024 per gain update. This permits sky samples to be acquired at intervals of 2.67 seconds for improved temporal resolution of cloud liquid water variations and better coordination with the millimeter cloud radar during IOPs. 3. Separation of zenith LOS observations from TIP data When the radiometer is in TIP mode, the zenith LOS observations are now extracted, the PWV and LWP computed and reported separately in the output file. This eliminates the periods of missing LOS data during calibration checks/updates. 4. Automatic self-calibration The software now permits the calibration to be updated at specified intervals or continuously. In the first case, LOS mode is automatically changed to TIP mode at user-specified intervals or whenever clear sky conditions occur, the tip data reduced, the calibration updated ,and the radiometer returned to LOS mode without operator intervention. In the second case, the radiometer is continuously is TIP mode until changed by the operator. 5. Graphical user display The graphical display is comprised of a status display, a message display, a temperature plot, a plot of the retrieved PWV and LWP, and (in TIP mode) a plot of the latest tip curves. Editor's Note: The SGP.C1 data were reprocessed in 2004 and enhancement #3 described above was applied to the data prior to Oct 1998. The SGP.BF data are queued for reprocessing as well. |

Subject: | SGP/MWR/B1/B4/B5/B6/C1 - software upgrade (version 3.27) |

Description: | At 00:00 GMT on 7 January version 3.27 of the MWR operating program was installed and made operational at the SGP central facility (C1). No problems were noted over the next few days and the boundary facility MWRs (B1, B4, B5, B6) were upgraded at 20:00 GMT on 11 January. This version includes a beam width correction I developed as well as providing the capability to automatically level the elevation mirror (that is, to automatically detect and correct offsets in the elevation angle stepper motor position.) On 12 January I discovered that the '486-based MWR computers at B1, B4 and B6 were not executing the system command to move and rename the data files so that the ARM data system could retrieve them. Reducing the length of the storage arrays in the auto-leveling feature from 1000 to 250 resolved the problem. This results in the auto-leveling being based on only 4 hours of clear sky data rather than 16 hours at B5 and C1. This version of the program is 3.28. Version 3.27 (running at B5 and C1) can be installed if and when these computers are upgraded to Pentium-class machines. The improvement in the quality of the tip curves resulting from the auto-leveling has been dramatic: differences in the brightness temperatures at 3 airmasses (19.5 and 160.5 degrees) have been reduced from +/- 5 K to +/- 0.5 K. The goodness-of-fit coefficient for the tip curves has improved from about 0.995 to over 0.998. In order to take full advantage of this improvement to detect and reject cloudy tip curves, the minimum value of the goodness-of-fit coefficient for a valid tip curve has been increased from 0.995 to 0.998. Editor's Note: The SGP.C1 data were reprocessed in 2004 to produce a common DOD for all time. The 1996-1998 data reprocessing included beam width and mirror-leveling corrections, but the data prior to that range did not have these corrections applied. |
