Global Center Table
Global Horizontal Center Table: (back row) MS-410, MS-80, SR25, MS-210W, GPP, PSP RG780, MS-802; (front row) TSP-700, UVB-1, TUVR, SPP (vent.), PSP (vent.). On 12/19/2023, the SPP and PSP were removed from ventilator and the SR25 and new SR20 (not shown) were installed in the same ventilators.
Global East Table
Global Horizontal East Table: UV-S-A-T, UV-S-B-T, SP-510, SL-510, ML-01, CMP22 (vent.), LI-200R, LI-200, LI-210, LI-190, and SP-110. An SPN1 (not shown) is located in the lower right corner of the table. The SL-510 was removed from service on 3/29/2023.
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).
WISER and SolarSIM-G
EKO MS-711 and MS-712 (WISER) spectroradiometer system mounted on the south-west corner of SRRL instrument platform. The SolarSIM-G is located on the far right. On 11/21/2023, a BTS2048-UV-S-WP (not shown) was installed just to the right of the SolarSIM-G.
Radiometer tower (North Eastern View)
Radiometer Tower (looking toward the north east): Global 40-South CMP22, Global 40-South SP-Lite2, Global 40-South LI-200, Global 40-South CUV4, Global 40-South Research Cells (not part of BMS), (6) upwelling instruments and (8) vertical pyranometers. SRRL's primary temperature and relative humidity probe is located on this tower (inside sun shield). The EFM-100 at the highest point measures atmospheric electric field.
Radiometer tower (Western View)
Radiometer Tower (looking toward the west): Upwelling PIR, Upwelling CG3, Upwelling CMP11, Upwelling CM3, Upwelling LI-200, and Upwelling LI-190. At the Global 90 North, East, South, and West positions are (4) PSP & (4) LI-200 pyranometers. A wind speed & direction sensor measures surface winds and is used to calculate wind chill factor.
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. On 08/09/2021, the AM16/32B was replaced with an AM25T MUX.
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
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.
Rain Gauge & Snow Depth
A TB4 rain gauge and SR50A snow depth sensor located 30 feet west of the radiometer tower.
Sky Imager
EKO/CMS-Schreder ASI-16 All Sky Imager mounted on the north end of instrument deck. On 11/6/2019, the ASI-16 was relocated to the south east corner of instrument deck.
1 & 2-axis Trackers
EKO STR-32G 2-axis (left) and 1-axis (right) solar trackers both containing the following BMS instrumentation: WISER, CMP22, SP-Lite2, LI-200R. The trackers also include research instrumentation. The 1-Axis WISER was moved to a new 40-degree south fixed tilt stand (not shown) on 04/28/2022.
MS-700 on OTF Roof
MS-700 Spectroradiometer located on the roof of OTF building (not at SRRL). The MS-700 was removed from OTF on 01/27/2023 and relocated to the SRRL Radiometer Tower on 04/06/2023 measuring upwelling spectra (not shown).
MS-700 Field of View
The field of view as seen by MS-700 spectroradiometer on OTF building (not at SRRL).

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