TLALOCNet EAR-1338091 Annual Report September 1, 2014 - August 31, 2015 (FY2015) SUMMARY This annual report covers TLALOCNet project (EAR-1338091) “MRI: TLALOCNet - Development of a continuous GPS-MET array in Mexico for atmospheric, climatic, and seismotectonic research in the Americas” activities for the time period from September 1, 2014 to August 31, 2015. TLALOCNet is a collaborative project with multiple institutional PIs, under a single award from the National Science Foundation to UNAVCO on August 16, 2013. The project is directed by M. Meghan Miller, as PI, with Glen Mattioli, Enrique Cabral, Chuck DeMets, and Yolande Serra acting as Co-PIs. Glen Mattioli is acting as Project Director in his role as Director of Geodetic Infrastructure at UNAVCO; Karl Feaux is the Project Lead in his role as the GPS Operations Manager for the PBO, and John Galetzka is the Project Manager.

Figure 1. TLALOCNet operating and planned stations: 14 installed NSF cGPS-Met stations (yellow dots) and 11 planned stations (red dots), which remain to be installed. Data from 13 UNAM contribution stations (green dots) will be included in the TLALOCNet archives. Other NSF-funded stations, from COCONet (orange dots) and the PBO El-Major Cucapah Earthquake (blue dots) projects also are shown on this map.

To date, UNAVCO engineering personnel have retrofitted 4 existing stations and installed 10 new stations (Table 1) for a total of 14 completed stations to date. Another retrofitted station—PZUL—will be rejected as a TLALOCNet station because of deteriorating security and cellular data communications at the site. At least 8 additional stations will be installed by December 1st, 2015, and any remaining stations, including GUAX, should be installed and online by March 1st, 2016, which will bring the final total to 25 at the close of construction.

OPERATIONS SUMMARY The major milestones for this reporting period (9/1/14 to 8/31/15) were the reconnaissance and the receipt of permits at twenty sites as well as the full execution of a Memorandum of Understanding between UNAVCO and UNAM. This MOU defines UNAM as the permit holder for all TLALOCNet sites, but gives UNAVCO personnel the authorization to work at these locations. Continued progress toward station installation occurred along with other preparation for final installations. There was only one required maintenance visit in the last year; no cases of vandalism occurred at any of the TLALOCNet stations.

Other project operational highlights include:

• Started “Donation-to-UNAM #2” paperwork and shipping process of remaining heavy and expendable equipment in October 2014—delivered to UNAM in May 2015.

• Hired a Mexican contract worker, Luis Salazar Tlaczani, to assist UNAVCO with station installation and maintenance.

• Completed the installation of the Regional Data Center at the University of Guadalajara. • Completed installations of stations TNCM, TNMR, TNAT, TNNX, TNPJ, TNTB, TNPP,

TNBA, YESX, TNAM, TNMS, and PZUL. • Completed the network monitoring tools to assist managers and engineers in station

maintenance. On-going and other future work includes:

• Eight stations are scheduled for installation by December 1, 2015. • Remaining 3 stations will be installed by March 1, 2016. • Maximize the number of stations providing high-rate data (1 Hz) streams in real-time (<1

s latency). • Add meteorological instruments to all contributing stations. • Completion of the TLALOCNet webpage and initiation of live website.

Site and Schedule Changes A teleconference was conducted on October 17th, 2014 between the PIs, TLALOCNet project lead, and project manager to provide a project status report and decide on several site relocations. Two proposed sites In Guerrero (OXTP and PAPA) and one in Michoacan (CALC) were found unsuitable by John Galetzka, and after discussion, the PIs decided to shift those sites to locations in northwest Mexico (Topolobampo, Puerto Penasco, and GUAX). There were delays in the arrival of equipment donation #2 at UNAM before Easter 2015. The delays caused the schedule for these installations to be pushed back until fall 2015, when the weather is more agreeable for fieldwork. We anticipate that additional installations will resume in September 2015, and at least eight additional stations will be operational by December 1st, 2015. Any remaining proposed sites, including GUAX, should be installed and online by March 1st, 2016, which will bring the construction phase of TLALOCNet to a close. Regional Data Center For three days in early December 2014 in Boulder, UNAVCO Geodetic Data Services staff trained future COCONet and TLALOCNet Regional Data Center (RDC) operators in a GSAC and Dataworks software. In February 2015, UNAVCO staff delivered the TLALOCNet Regional Data Center system to U.S. Embassy in Mexico City using the Department of State diplomatic pouch service. The system consists of a virtual machine (VM) that has been provisioned with the Linux operating system and systems software including web server, web application server, ftp server, Java, Perl, Python, Dataworks, and MySQL, plus the GSAC database, GSAC software, and required synchronization scripts. The TLALOCNet RDC system now resides and is successfully operating at the University of Guadalajara.

Table 3. TLALOCNet Status: Tasks completed in during this reporting period. In-Country Independent Contractor Luis Salazar was hired by UNAVCO as an independent contractor in May 2014 to perform various tasks related to GNSS station reconnaissance, permitting, installation, maintenance, and other activities in support of the NSF-funded TLALOCNet project. Luis has proven himself an invaluable team member, and always accompanies and assists UNAVCO field engineers, while they are working in Mexico. SCIENTIFIC EFFORTS: ACTIVITIES, SUBMITTED MANUSCRIPTS AND ABSTRACTS Kirk Holub from NOAA has agreed to process in real-time GPS PWV from TLALOCNet and other real-time stations in Mexico. The 2015 North American monsoon, which is currently underway, will be observed using the seven new TLALOCNet stations in northwestern Mexico, and those of several other stakeholder institutions. We anticipate that these observations and the GPS-derived PW products will provide an unprecedented data set for the academic atmospheric science community and other TLALOCNet stakeholders.

DATA SUMMARY UNAVCO currently archives standard 15 sec hourly data files from 14 UNAVCO-built GPS-Met stations, and 10 Mexican-contributed GPS-Met stations. Additionally, there are currently 7 TLALOCNet stations delivering high-rate, low-latency (1 Hz, < 2 s) data streams in real-time via the Networked Transport of RTCM via Internet Protocol (NTRIP); these RT-GPS stations are part of the UNAVCO RT network of >450 stations, which is managed through the proprietary PIVOT software package from Trimble Navigation, Inc.

BUDGET AND SCHEDULE Including open commitments (project manager salary, travel to support remaining scope, and the purchase of remaining project hardware), the TLALOCNet expenditures through the end of June 2015 were $992,485. With a June 2015 project budget (through 22 months) of $1,087,637, the project is within a 10% cost variance. The delay in the first year hiring of the project manager has pushed the expected network completion of all stations to March 2016. The project is in a good position, however, to meet all installation goals in Year 3, within the proposed budget. UNAVCO engineering staff installed 3 cGNSS-Met stations in the first year and 11 stations in the second year of the TLALOCNet project. Because the project manager was not hired until the 8th month of the first year of the project, the original, overly optimistic, 2-year installation schedule has not been met. The project, however, remains appropriately under budget based on the number of stations installed to date and is in a good position to finish the installations in during the final year (9/1/15 to 8/31/16). UNAM installed 4 required cost-share stations in the first year and 7 more were completed in the second year of the project (Figure 2 and 3). All data from the UNAM contributing stations are delivered via daily ftp to the UNAVCO data archive. Additional project milestones, such as completion of the regional data center and the project web page, are shown in the detailed project schedule (Figure 4).

EDUCATION, OUTREACH, AND COMMUNITY ENGAGEMENT In addition to our focus on logistics and station construction during the second year, the TLALOCNet project set up the Regional Data Center and PIs and UNAVCO staff reported about progress at two major geophysical conferences. On the occasion of the 30th anniversary of the devastating Mw 8.1 earthquake in Mexico, UNAVCO has been invited to participate at a symposium called "Sismo 85: Advances and challenges in seismology, engineering and risk management 30 years after the 1985 earthquake" at the Universidad Nacional Autonoma de Mexico (UNAM) campus in Mexico CIty. UNAVCO staff is working to provide speakers for sessions on networks and earthquakes and educational/outreach. Meetings and Conferences An invited talk about the initial development of TLALOCNet was given at the UGM annual meeting in Puerto Vallarta, Mexico in November 2014, and one poster was presented at Fall AGU in December 2015. As the project construction phase moves toward completion, we anticipate that a special session at AGU or GSA will be developed by the PIs to highlight new and upgraded TLALOCNet infrastructure (instruments and IT), data, data products, and analysis. PROJECT CONCERNS Additional time and effort to find and construct alternative sites: Adverse conditions at one operating station and six proposed stations required UNAVCO staff in close consultation with the PI team and our regional partners to select seven alternative sites. The conditions range from newly identified monument/geologic instability (two sites), required use of costly satellite telemetry (two sites), deteriorating security (one site), and restriction from using any form of telemetry (one site). Risk mitigation: We anticipate selecting and permitting seven alternative sites by November 1st, 2015, and having those stations operational by February 1st, 2016.
