The International Meridian Circle Program (IMCP) has made significant progress through the joint hard work of scientists from around the world. We are pleased to invite you to attend an IMCP workshop, scheduled for June 11–14, 2025, in Sichuan Province, China.
On June 12, 2025, there will be a half-day Big Science Program session and a dedicated half-day IMCP session. During the IMCP session, we will invite close partners, collaborators, and international organizations from the relevant research fields to join us in exploring new opportunities for scientific collaboration and discovery.
Following the session in Chengdu, Sichuan—famous for its giant pandas and cuisine—the IMCP Workshop will continue in Daocheng. Participants will visit the Solar Radio Telescope Array, a cutting-edge facility of the Chinese Meridian Project, located in Daocheng Yading, a natural wonder on the eastern Qinghai-Tibet Plateau, about 800 kilometers from Chengdu.

Warning regarding the Daocheng Yading Visit：
1. Considering that this activity will take participants to an altitude of over 4000 meters, experts participating in this event will voluntarily go after signing an informed consent form. They should also be aware of risks such as altitude sickness.
2. The climate at high altitudes is unpredictable with significant temperature fluctuations. The perceived temperature is often very low, so it is recommended to wear winter clothing, hats, and other cold-weather gear to prevent catching a cold, which is one of the main triggers for acute high-altitude pulmonary edema. It might rain during the trip, so be sure to bring rain gear. On sunny days, UV radiation can be strong, so prepare sun protection items like hats and masks. The air at high altitudes is dry, so remember to bring lip balm and other skincare products.
3. Upon first arriving at high altitude, everyone may experience varying degrees of symptoms related to oxygen deficiency, such as chest tightness, shortness of breath, and difficulty breathing. In more severe cases, there may be headaches, muscle aches, and insomnia. However, this does not mean you cannot adapt to the altitude—these reactions are normal. It is important to maintain a positive mindset and overcome altitude sickness. Self-mental suggestion is key.
4. When you first arrive at high altitude, avoid overeating or eating heavy meals, as this could burden your digestive system and make it harder to adapt to the environment. It is best to refrain from alcohol and smoking. Eat plenty of vegetables and fruits rich in vitamins, and drink plenty of water.
5. During the first days at high altitude, especially on the first day, avoid squatting, walking too fast, running, or doing any strenuous physical activities. Rest and breathe deeply. For the first few days, try to avoid taking hot baths.
