Three weeks passed since the first instruments where switched on around 26 November. Even though the actual hardware implementation did not take much more than 3 days, all members of the DACAPO-PESO team are working hard on getting the processing chain for the data up and running.

It was decided to implement a two-stage data processing. First processing is done on a server on-site in Punta Arenas. One 120-TB machine collects all data from the individual instruments of LACROS and frequent quicklooks are created. During night time, when network traffic at UMAG is low, most data is being transferred to the central remote sensing server of TROPOS in Leipzig. Only the raw spectra of 35-GHz radar is excluded from this data transfer.

Everybody is invited to have a look at the quicklooks of the DACAPO-PESO observations. Below is a list of links to most of the measurement quicklooks.

During the last week - 26 to 30 November - we set up the instruments of LACROS. Together with our colleagues of the Laboratorio de Investigaciones Atmosféricas (LIA) at the Universidad de Magallanes we had a couple of busy days. The ‘hardware’ work, like moving boxes, fixing and levelling the instruments in the right places, installing cables, etc., took the first half of the week. Furthermore, we had to dig a water and windproof cable trench between the containers and repair some smaller transport damages.

Additionally to the container site, we deployed some radiation measuring equipment on the rooftop platform of the LIA. This installation required a little bit of tinkering, as we had to adapt to the local conditions. Luckily, the weather was quite nice during this period. Mostly sunny with almost no wind and rain.

Having the ‘hardware’ part done, the second half of the week was devoted to software setup. The network had to be configured, internet access had to obtained, synchronization scripts need adjustment (or rewriting), the on-site data processing had to be set up and a lot more.

On Friday the 30 November 2018 Boris Barja organized a small inauguration event, to officially start the observation phase of DACAPO-PESO. On this occasion, representatives of the university and local media had the chance to visit the site and have a look at the instrumentation.

The DACAPO-PESO deployment of LACROS is about to become serious. A one-person advance party already arrived at Punta Arenas last weekend. During the week, some logistics had to be prepared and coordinated with our colleagues of UMAG and  some local companies.

On Friday, the 23 November, the two containers with the instruments finally arrived at UMAG, Punta Arenas. Two trucks, a crane and several slingers were at the site before 7 o’clock in the morning. Together with staff from TROPOS and UMAG, locating the containers on the prepared concrete bedplates went smoothly.

Following the first impression, the containers seemed to have survived the 2-month sea transport rather well. As a last task for this day, the electricity connection was installed and the air conditioning/heating was powered up.

The instruments will be set up and put to operation during next week, as soon as two more scientists from TROPOS arrive here. Let’s hope that nothing (too serious) broke during transport.
