On 10/17/2017, the CUVA1 and CUVB1 were removed from service. On 12/1/2017, the SR25 and a new MS-80 were mounted in place of the CUVA1/CUVB1; In addition, the TSP-700 was moved in the place of the 501A and the 501A was relocated to the west table.
Global East Table
Global Horizontal East Table: UV-S-A-T, UV-S-B-T, ML-01, CMP22 (vent.), LI-200R, LI-200, LI-210, LI-190, and SP-110. The SR25 (not shown) is located below the CMP22 and the SPN1 (not shown) is located in the lower right corner of the table. On 12/1/2017, the SR25 was relocated to the center table and an Apogee SP-510 & SL-510 (neither shown) were mounted next to the ML-01.
CR3000 and (3) MUXs
A CR3000 datalogger with (2) AM25T MUXs and (1) AM16/32B MUX collect data from all instruments on deck and the Upwelling PIR/CG3/CM21 on the radiometer tower. System is located in a drawer under the patch panel inside the SRRL data lab.
Shadowband PSP
Diffuse and Zebra Shadowband PSP instruments mounted on the north east corner of instrument deck. Note: Data collection from the Zebra was discontinued on 12/11/2014. On 6/26/2017, the Shadowband PSP was replaced with an 8-48 (not shown).
EKO MS-701, MS-710, and MS-712 (WISER) spectroradiometer system mounted on the south-west corner of SRRL instrument platform. The WISER system can be mounted for global or direct normal measurements (requires DNI tubes and solar tracker, not shown). On 9/8/2017, the MS-701 and MS-710 were replaced with an MS-711 (not shown).
Radiometer tower (Eastern View)
Radiometer Tower (looking toward the east): Global Normal CM21, Global 40-South PSP, Global 40-South LI-200, Global LI-190, Global LI-210, (4) upwelling instruments, (8) vertical pyranometers, and a CNR1 (which consists of 4 instruments). A wind speed & direction sensor measures surface winds and is used to calculate wind chill factor. The EFM-100 (not shown) was added to the top of the tower (to the north of the CM21) on 9/27/2010. The Global 40-South PSP was replaced with a CMP11 (not shown) on 4/9/2015. The Global LI-190 and LI-210 were relocated to the instrument platform on 3/10/2015. The CNR1 was disassembled in March 2015 and the two downwelling sensors were removed. The Global Normal CM21 was replaced with a CMP11 (not shown) on 6/20/2015. On 12/1/2016, a Global Normal LI-200R (not shown) was added on the tracker. On 12/1/2017, the Global Normal CMP11 (not shown) was replaced with a CMP22 (not shown).
Radiometer tower (Western View)
Radiometer Tower (looking toward the west): Upwelling PIR, Upwelling PSP, Upwelling LI-200, Upwelling LI-190, and the CNR1. At the Global 90 North, East, South, and West positions are (4) PSP & (4) LI-200 pyranometers. The SRRL's primary temperature and relative humidity probe is located on this tower. A snow depth sensor is mounted on the north end of the tower. The Upwelling PSP was replaced with a CM21 (not shown) on 3/27/2015. The CNR1 was disassembled in March 2015 and the two downwelling sensors were removed. On 11/27/2017, the Upwelling CM21 (not shown) was replaced with a CMP11 (not shown). On 1/17/2018, the Snow Depth sensor was relocated to a new stand 30 feet to the west of radiometer tower.
CR3000 and MUX
A CR3000 datalogger with AM16/32B MUX collect data from all instruments on radiometer tower (except Upwelling PIR/CG3/CM21). Located under the MUX standoff is a pressure sensor and EFM-100 interface.
Deck WS/WD
RM Young wind speed and direction sensor is mounted 8 feet away from west side of instrument deck (3 feet from the stair case).
Yankee Total Sky Imager TSI-880 mounted on the north west end of instrument deck
SRRL SkyCam mounted on the south east end of instrument deck. The SkyCam was destoyed by hail storm on 5/8/2017 and was removed from service.
Rain Gauge
Rain gauge located 26 feet to the northwest of radiometer tower. The rain gauge was later relocated directly west of the radiometer tower after the completion of the SRRL Expansion in 2011. On 9/8/2017, the rain guage was upgraded to a TB4 mounted on a new pole (not shown) about 5 feet further to the west.
Met Tower
Meteorological Tower (located in Sun Edison PV field): Wind Speed & Direction @ 42 feet and Wind Speed & Direction @ 22 feet. The towers data acquisition system, located in white box, is powered by the small PV panel. The wind sensors were destroyed by hail storm on 5/8/2017. On 11/16/2017, the 22 foot level sensors were replaced and new booms with sensors at 33 feet were added (the 42 foot level was abandoned).
Meteorological Data Acquisition Tower (located in Sun Edison PV field): Datalogger, temperature and relative humidity probe, freewave radio, and communications antenna, which are powered by the PV panel.
SunEdison POA
A Global LI-200 pyranometer measuring the plane of array (POA) irradiance on a Sun Edison PV string. Under the LI-200 (in the small metal enclosure) is an inclinometer to measure the current angle of the Sun Edison 1-Axis tracking system.
A CR800 datalogger with FreeWave radio collect data from all sensors located on the Meterological Tower.

Photos of decommissioned or relocated instrumentation and trackers are also available.
